This book was released on 2010-04-24 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenomena occurring during a contact of two bodies are encountered in everyday life. In reality almost every type of motion is related to frictional contact between a moving body and a ground. Moreover, modeling of simple and more complex processes as nailing, cutting, vacuum pressing, movement of machines and their elements, rolling or, finally, a numerical simulation of car crash tests, requires taking contact into account. Therefore, its analysis has been a subject of many research efforts for a long time now. However, it is author’s opinion that there are relatively few efforts related to contact between structural elements, like beams, plates or shells. The purpose of this work is to fill this gap. It concerns the beam-to-beam contact as a specific case of the 3D solids contact. A numerical formulation of frictional contact for beams with two shapes of cross-section is derived. Further, a couple of effective methods for modeling of smooth curves representing beam axes are presented. A part of the book is also devoted to analyze some aspects of thermo-electro-mechanical coupling in contact of thermal and electric conductors. Analyses in every chapter are illustrated with numerical examples showing the performance of derived contact finite elements.

Book excerpt: STAY ALIVE ON THE FAR SIDE OF THE MOON What happens when you get the one thing you wanted most in life? Lonely 16-year-old farm girl Barbara Winton has been following one reality show for years. Then in an instant she goes from fangirl to participant when the call comes from Dr. Keegan Bright: She’s been selected out of a horde of applicants to join him on the Moon. She’ll be one of his Bright Sparks, six students with expertise in STEM and plenty of their own ingenuity chosen to work with Dr. Bright and given big responsibilities to undertake new projects important to the growth of the colony. Her first task? Build a radar telescope using an entire crater on the far side of the Moon. But Barbara soon learns that life on a burgeoning frontier outpost like the Moon is a far cry from safe, civilized Earth. The loner from farm country must find a way to weld a functional team out of fiercely independent thinkers. Not only are they a bit trickier to work with than farm robots, not only is the working environment incredibly dangerous—she also has to perform this miracle in front of millions of fans. . . .

Available in PDF, EPUB and Kindle. Book excerpt: Professor Yurii A. Anan'ev has a long-standing international reputation for his publications on optical beams and resonators. Now many of his contributions will be readily available for the first time in a book. The generation of maximum power, minimum divergence beams from laser resonators is probably the most important topic in quantum electronics and optics today. The only book of its kind, Laser Resonators and the Beam Divergence Problem covers not only the theory, but also the applications of resonators to real systems as opposed to idealized models. Each rigorous examination of an optical configuration is accompanied by a detailed discussion of its associated applications and of the considerations for the user in practical work. The book contains a wealth of information on the developments in resonator technology, including much material previously unavailable outside the Soviet Union. It is an essential reference source to every researcher in laser science and technology.

Available in PDF, EPUB and Kindle. Book excerpt: Laser and Ion Beam Modification of Materials is a compilation of materials from the proceedings of the symposium U: Material Synthesis and Modification by Ion beams and Laser Beams. This collection discusses the founding of the KANSAI Science City in Japan, and the structures, equipment, and research projects of two institutions are discussed pertaining to eV-MeV ion beams. A description of ion beams as used in materials research and in manufacturing processes, along with trends in ion implantation technology in semiconductors, is discussed. Research into ion beams by China and its industrial uses in non-semiconductor area is noted. For industrial applications, developing technology in terms of high speed, large surface modifications and use of high doses is important. Thus, the development of different ion beam approaches is examined. Industrial applications of ion and laser processing are discussed as cluster beams are used in solid state physics and chemistry. Mention is made on a high power discharge pumped solid state physics (ArF) excimer laser as a potential light source for better material processing. Under ion beam material processing is nanofabrication using focused ion beams, important for research work in mesoscopic systems. Progress in the use of ion-beam mixing using kinetic energy of ion-beams to mingle with pre-deposited surface layers of substrate materials has shown promise. Advanced materials researchers and scientists, as well as academicians in the field of nuclear physics, will find this collection helpful.
Download or read book An Isogeometric Approach to Beam Structures written by Buntara S. Gan and published by Springer. This book was released on 2017-06-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes a novel, original condensation method to beam formulation based on the isogeometric approach to reducing the degrees of freedom to conventional two-node beam elements. In this volume, the author defines the Buntara Condensation Formulation: a unique formulation in condensing the dynamic equilibrium equation for beam structures, suitable for reducing the number of unlimited dynamic equations necessary to yield a classic two-node beam element. Professor Buntara’s method overcomes the problem of the isogeometric approach where the number of degrees of freedom is increased along with the complexity of the geometrical beam element and facilitates implementation of the codes into the existing beam structures programs, and CAD geometrical data into the conventional FE beam element codes. The book proposes a new reduction method where the beam element can be treated as under the conventional beam element theory that has only two nodes at both ends.

Download or read book A New Kirchhoff Love Beam Element and its Application to Polymer Mechanics written by Matthias C. Schulz and published by Springer Nature. This book was released on 2022-09-21 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The novel finite element formulations fall into the category of geometrically exact Kirchhoff-Love beams. A prominent characteristic of this category is that the absence of shear deformation is strongly enforced by removing two degrees of freedom. Further, the corresponding beam theories exhibit not only translational but also rotational degrees of freedom and their configurations thus form a non-additive and non-commutative space. Sophisticated interpolation schemes are required that need to be tested not only for locking, spatial convergence behavior, and energy conservation, but also for observer invariance and path-independence. For the three novel beam element formulations all these properties are analytically and numerically studied and confirmed, if applicable. Two different rotation parameterization strategies are employed based on the well-known geodesic interpolation used in many Simo-Reissner beams and the lesser known split into the so-called \textit{smallest rotation} and a torsional part. Application of the former parameterization results in a mixed finite element formulation intrinsically free of locking phenomena. Additionally, the first geometrically exact Kirchhoff-Love beam element is presented, which strongly enforces inextensibility by removing another degree of freedom. Furthermore, the numerical efficiency of the new beam formulations is compared to other beam elements that allow for or suppress shear deformation. When modeling very slender beams, the new elements offer distinct numerical advantages. Standard molecular dynamics simulations, which are commonly used to study polymers, suffer from a lack of a careful mathematical basis and the use of an expensive explicit time integration scheme. To circumvent these shortcomings and to be able to simulate stretching experiments on relevant time scales, the problem is described by a stochastic partial differential equation, which can be solved using the finite element method with a backward Euler temporal discretization. In detail, the polymer is represented by a Kirchhoff-Love beam with a linear elastic constitutive model. Inertial and electrostatic forces are neglected. It is deformed by a distributed load mimicking collisions with molecules of the surrounding fluid. Naturally, this load heavily fluctuates over time and space and mean values need to be computed in a Monte Carlo manner. To vastly speed up the fitting process to experimental data in a Bayesian framework, a surrogate model based on a Gaussian process is set up, which directly computes the mean values for given material parameters. The uncertainties and correlations of the material parameters are studied and compared to the literature.

This book was released on 2012-12-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of nonlinear optics has witnessed a tremendous evolution since its beginnings in the early sixties. Its frontiers have been extended in many direc tions and its techniques have intruded upon many areas of both fundamental and practical interest. The field itself has been enriched with many new phe nomena and concepts that have further extended its scope and strengthened its connection with other areas. As a consequence, it is becoming increasingly unrealistic to expect to cover the different facets and trends of this field in the lectures or proceed ings of a summer school, however advanced these may be. However much of the current progress and interest in this field springs to a large extent from the promise and expectation that highly performing all-optical devices that exploit and operate on the principles of nonlinear optics will constitute an important branch of future technology and will provide new alternatives in information processing and transmission. The conception of new devices, in general, requires an intricate and bold combination of facts and methods from most diverse fields, in order to perform functions and operations that fit into an overall technological ensemble.

This book was released on 2006-04-11 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of nonlinear optics, which has undergone a very rapid development since the discovery of lasers in the early sixties, continues to be an active and rapidly developing - search area. The interest is mainly due to the potential applications of nonlinear optics: - rectly in telecommunications for high rate data transmission, image processing and recognition or indirectly from the possibility of obtaining large wavelength range tuneable lasers for applications in industry, medicine, biology, data storage and retrieval, etc. New phenomena and materials continue to appear regularly, renewing the field. This has proven to be especially true over the last five years. New materials such as organics have been developed with very large second- and third-order nonlinear optical responses. Imp- tant developments in the areas of photorefractivity, all optical phenomena, frequency conv- sion and electro-optics have been observed. In parallel, a number of new phenomena have been reported, some of them challenging the previously held concepts. For example, solitons based on second-order nonlinearities have been observed in photorefractive materials and frequency doubling crystals, destroying the perception that third order nonlinearities are - quired for their generation and propagation. New ways of creating and manipulating nonl- ear optical materials have been developed. An example is the creation of highly nonlinear (second-order active) polymers by static electric field, photo-assisted or all-optical poling. Nonlinear optics involves, by definition, the product of electromagnetic fields. As a con- quence, it leads to the beam control.
