Available in PDF, EPUB and Kindle. Book excerpt: While the theory and application of finite elements methods can be extended to incompatible, hybrid, and mixed element methods, important issues, such as determining the reliability of the solution of incompatible multivariable elements, along with a common perception of impracticality, have hindered the widespread implementation of these methods.

Available in PDF, EPUB and Kindle. Book excerpt: Plasticity and Geotechnics is the first attempt to summarize and present in a single volume the major achievements in the field of plasticity theory for geotechnical materials and its applications to geotechnical analysis and design. The book emerges from the author’s belief that there is an urgent need for the geotechnical and solid mechanics community to have a unified presentation of plasticity theory and its application to geotechnical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Classical plasticity is a well established domain of mechanics and engineering, providing the basis for many engineering structural design, manufacturing processes and natural phenomena. New important characteristics are emerging in the interdisciplinary approach of micro-, meso- and macro-mechanics, and through analysis, experiments and computation.The interaction of mechanics and materials scientists is introducing tremendous changes in the two disciplines, so that the possibility of materials being processed on the microscale to achieve the desired macroscopic properties is rapidly approaching.A comprehensive overview on the latest developments in both macroplasticity and microplasticity theories, their interactions and applications in various engineering disciplines such as solid mechanics, structural analysis and geo-mechanics, materials science and technology, and metal forming and machining, is given in this volume. Case studies written by international experts focus on aspects such as the applications of plasticity in interdisciplinary and non-conventional areas. The 150 papers provide a current and useful reference source on the latest advances for both research workers and engineers in the various fields of plasticity.

This book was released on 2009-02-22 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: To predict loading limits for structures and structural elements is one of the oldest and most important tasks of engineers. Among the theoretical and numericalmethodsavailableforthispurpose,so-called“DirectMethods”,- bracing Limit- and Shakedown Analysis, play an eminent role due to the fact that they allow rapid access to the requested information in mathematically constructive manners. The collection of papers in this book is the outcome of a workshop held at Aachen University of Technology in November 2007. The individual c- tributions stem in particular from the areas of new numerical developments renderingthemethodsmoreattractive forindustrialdesign,extensionsofthe general methodology to new horizons of application, probabilistic approaches and concrete technological applications. The papers are arranged according to the order of the presentations in the workshop and give an excellent insight into state-of-the-art developments in this broad and growing ?eld of research. The editors warmly thank all the scientists, who have contributed by their outstanding papers to the quality of this edition. Special thanks go to Jaan Simon for his great help in putting together the manuscript to its ?nal shape.

This book was released on 2014-08-11 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viscoelastic materials like solid propellant grains exhibit material properties, which are timedependent and incompressible in nature. The displacement based finite elements fails to solve structural problem having incompressible materials. The basic reason is Poisson's ratio approaches 0.5 for such materials. Which makes the constitutive relation between stress and strain very stiff there by the stiffness matrix becomes very stiff which yields very poor displacement results and predicted stresses and strains are unreliable. This phenomenon is known as volumetric locking. To overcome this difficulty special formulations are needed to address such materials. There are many methods available in literature like Hybrid-stress displacement formulation, B-Bar method and Herrmann formulation etc. This project is proposed to develop 8-noded quadrilateral, 9-noded quadrilateral and 6 noded triangular axisymmetric finite elements based on Herrmann formulation to overcome the difficulty of incompressible materials. The developed elements will be studied for its applicability for the ranges of Poisson's ratio and for distortion sensitiveness.

This book was released on 1974 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The theory and computer program for an axisymmetric finite element for static stress and deflection analysis is presented. The element is an eight noded isoparametric quadrilateral based on the displacement method which is capable of representing quadratic variation of element boundaries and displacements. Element stiffness properties are developed for linear elastic small displacement theory using homogeneous isotropic material. Test cases are compared with theoretical solutions from the theory of elasticity to identify program capabilities and limitations. Ability to analyse axisymmetric problems and to represent curved element boundaries has been demonstrated. Example problems including a cylindrical pressure vessel, a disk of uniform thickness subjected to centrifugal body force, and stress concentrations in a cylindrical rod due to a spherical inclusion are presented. In each of these cases program predicted deflection and stress values were within 2% of theoretical values. Limitations which have been identified include the prediction of discontinuous stresses at adjacent element boundaries, failure to match original element boundary stress conditions in substructure analyses, and the necessity of double precision calculations to correctly analyse problems whose theoretical solutions obey small displacement plate theory. Analysis of a spherical pressure vessel resulted in predicted displacements within 4% of theoretical values while stresses on element boundaries varied by 60% from theoretical values. Substructure analysis for the spherical inclusion problem resulted in prediction of boundary stresses which were incompatible with those originally obtained. Techniques to overcome this difficulty are proposed but are not tested. The inability to obtain reasonable results for flexural problems was found to be due to round off error in the single precision technique used for solving the structure equilibrium relations. Use of double precision calculations resulted in displacements and stresses within .25% and 4.% respectively of theory for the case of a clamped circular plate loaded by a uniform pressure normal to its surface."--Abstract.
