This book was released on 2006 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: An improved transient nonlinear finite element program was developed to solve coupled-field problems with field-dependent material properties. The program was applied to three problems: (i) Determining the tolerance of transmission class solid dielectric cable to conducting contaminants as defined by the maximum size of the worst-case metallic contaminant that will not cause failure during operation, as a function of the operating field of the cable dielectric. This problem requires computing the space charge limited field at the tip of the defect in cross-linked polyethylene, the electric conductivity of which is a function of electric field and temperature. The calculated maximum tolerable defect size agrees well with empirical data. (ii) The effect of convective heat transfer in a tank-type metal oxide surge arrester during the IEC thermal stability Type Test, during which the arrester is first heated by two current pulses that increase substantially the low field conductivity of the arrester elements (ZnO), after which an AC voltage is applied for 30 minutes to determine if the arrester will remain stable. Simulating this test requires calculating the AC power dissipation in the ZnO element stack as a function of electric field and temperature, as well as the heat dissipation through the complex thermal circuit of the arrester. Simulation results show that by increasing convective heat transfer through forced convection, the required ZnO mass can be reduced by half. (iii) The cooling effects of Al heat sinks placed between arrester elements to improve arrester thermal stability. The distribution of power dissipation in the arrester elements caused by the operating AC voltage was computed as a function of axial position and time after adiabatic heating of the arrester elements. This problem requires 2-D finite element computation of the electric and thermal fields in a highly nonlinear system. The use of heat-of-fusion heat sinks, which melt at low temperature and can 'clamp' the ZnO temperature, was also investigated.

This book was released on 2012-07-30 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic introduction to the theories and formulations of the explicit finite element method As numerical technology continues to grow and evolve with industrial applications, understanding the explicit finite element method has become increasingly important, particularly in the areas of crashworthiness, metal forming, and impact engineering. Introduction to the Explicit Finite Element Method for Nonlinear Transient Dynamics is the first book to address specifically what is now accepted as the most successful numerical tool for nonlinear transient dynamics. The book aids readers in mastering the explicit finite element method and programming code without requiring extensive background knowledge of the general finite element. The authors present topics relating to the variational principle, numerical procedure, mechanical formulation, and fundamental achievements of the convergence theory. In addition, key topics and techniques are provided in four clearly organized sections: • Fundamentals explores a framework of the explicit finite element method for nonlinear transient dynamics and highlights achievements related to the convergence theory • Element Technology discusses four-node, three-node, eight-node, and two-node element theories • Material Models outlines models of plasticity and other nonlinear materials as well as the mechanics model of ductile damage • Contact and Constraint Conditions covers subjects related to three-dimensional surface contact, with examples solved analytically, as well as discussions on kinematic constraint conditions Throughout the book, vivid figures illustrate the ideas and key features of the explicit finite element method. Examples clearly present results, featuring both theoretical assessments and industrial applications. Introduction to the Explicit Finite Element Method for Nonlinear Transient Dynamics is an ideal book for both engineers who require more theoretical discussions and for theoreticians searching for interesting and challenging research topics. The book also serves as an excellent resource for courses on applied mathematics, applied mechanics, and numerical methods at the graduate level.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the theory and computer implementation of the finite element method as applied to nonlinear problems of heat transfer and similar field problems, fluid mechanics (flows of incompressible fluids), and solid mechanics (elasticity, beams and plates). Both geometric as well as material nonlinearities are considered, and static and transient (i.e. time-dependent) responses are studied. Although there exist a number of books on nonlinear finite elements that serve asgood references for engineers who are familiar with the subject and wish to learn advanced topics or the latest developments, there is currently no book which is suitable as a textbook for a first course on nonlinear finite element analysis. This book fills the void in the market, providing a clearunderstanding of the concepts of nonlinear finite element analyses through detailed theoretical formulations and computer implementation steps, examples and exercises. In addition, the book serves as a prelude to more advanced books on the subject.

This book was released on 1996-08-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat transfer analysis is a problem of major significance in a vast range of industrial applications. These extend over the fields of mechanical engineering, aeronautical engineering, chemical engineering and numerous applications in civil and electrical engineering. If one considers the heat conduction equation alone the number of practical problems amenable to solution is extensive. Expansion of the work to include features such as phase change, coupled heat and mass transfer, and thermal stress analysis provides the engineer with the capability to address a further series of key engineering problems. The complexity of practical problems is such that closed form solutions are not generally possible. The use of numerical techniques to solve such problems is therefore considered essential, and this book presents the use of the powerful finite element method in heat transfer analysis. Starting with the fundamental general heat conduction equation, the book moves on to consider the solution of linear steady state heat conduction problems, transient analyses and non-linear examples. Problems of melting and solidification are then considered at length followed by a chapter on convection. The application of heat and mass transfer to drying problems and the calculation of both thermal and shrinkage stresses conclude the book. Numerical examples are used to illustrate the basic concepts introduced. This book is the outcome of the teaching and research experience of the authors over a period of more than 20 years.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the finite element method applied to the resolution of industrial heat transfer problems. Starting from steady conduction, the method is gradually extended to transient regimes, to traditional non-linearities, and to convective phenomena. Coupled problems involving heat transfer are then presented. Three types of couplings are discussed: coupling through boundary conditions (such as radiative heat transfer in cavities), addition of state variables (such as metallurgical phase change), and coupling through partial differential equations (such as electrical phenomena). A review of the various thermal phenomena is drawn up, which an engineer can simulate. The methods presented will enable the reader to achieve optimal use from finite element software and also to develop new applications.

This book was released on 2019-05-21 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of combined extreme transient loadings on a structure is not well understood—whether the source is man-made, such as an explosion and fire, or natural, such as an earthquake or extreme wind loading. A critical assessment of current knowledge is timely (with Fukushima-like disasters or terrorist threats). The central issue in all these problems is structural integrity, along with their transient nature, their unexpectedness, and often the uncertainty behind their cause. No single traditional scientific discipline provides complete answers, rather, a number of tools need to be brought together: nonlinear dynamics, probability theory, some understanding of the physical nature of the problem, as well as modeling and computational techniques for representing inelastic behavior mechanisms. Nonlinear Dynamics of Structures Under Extreme Transient Loads covers model building for different engineering structures and provides detailed presentations of extreme loading conditions. A number of illustrations are given quantifying; a plane crash or explosion induced impact loading, the effects of strong earthquake motion, and the impact and long-duration effects of strong stormy winds—along with a relevant framework for using modern computational tools. The book considers the levels of reserve in existing structures, and ways of reducing the negative impact of high-risk situations by employing sounder design procedures.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains a collection of papers presented at the Europe-US Symposium on Finite Element Methods for Nonlinear Problems. The symposium was held at the Norwegian Institute of Technology, Trondheim, Norway during August 12 to 16, 1985. The finite element method has during recent years gained a position as the most important discipline in computational mechanics. The basis for this method was laid out about two decades ago, and linear finite element techniques are today well established and well understood. Much work is still being done in order to make these linear methods more efficient and reliable. However, a sub stantial part of the current research efforts in the finite element field is focused on developing the nonlinear capabilities of the method. This task is highly challenging and demanding, both from a theoretical and practical point of view. It was in this spirit that the Europe-US Symposium on Finite Element Methods for Nonlinear Problems was organized. The meeting may be seen as the continuation of the US-Germany Symposium on Finite Element Methods held in 1976 at MIT, Cambridge, USA and the Europe- US Workshop on Nonlinear Finite Element Analysis in Structural Mechanics held in 1980 at the Ruhr-Universitat, Bochum, West-Germany.
