    further, giving it a more rigorous foundation based on thermodynamics principles, and brought with it the need to consider many numerical and computational aspects to the plasticity problem. Observations from Standard Tests In this section, a number of phenomena observed in the material testing of metals will be noted.

    Plasticity Theory Book Summary: The aim of Plasticity Theory is to provide a comprehensive introduction to the contemporary state of knowledge in basic plasticity theory and to its applications. It treats several areas not commonly found between the covers of a single book: the physics of plasticity, constitutive theory, dynamic plasticity, large-deformation plasticity, and numerical methods. The approach to plasticity theory developed here is firmly rooted in thermodynamics. Emphasis is placed on the use of potentials and the derivation of incremental response, necessary for numerical analysis. The derivation of constitutive models for irreversible behaviour entirely from two scalar potentials is : $

      As a valuable reference source, this book presents a detailed and complete treatment of continuum mechanics and thermodynamics for graduates and advanced undergraduates in engineering, physics and mathematics. The chapters on plasticity discuss the standard isotropic theories and, in addition, crystal plasticity and gradient plasticity. The book deals with experimental observations on metals, composites, polymers and shape memory alloys, and the corresponding cyclic plasticity models for metals, polymers, particle reinforced metal matrix composites and shape memory alloys.

Abstract: In this work the relation of plastic and rheological material models is analysed in the framework of non-equilibrium thermodynamics. After a short summary of the basic notions of classical elasticity and plasticity the traditional thermodynamic treatment of plasticity by Ziegler is introduced, where the plastic deformation is an internal variable, leading to the reduction of Author: Ván Péter.

This book not only contains the fundamentals of continuum mechanics, plasticity, and viscoelasticity for the purpose of a text book but also sheds light on state-of the-art. research areas, for example, modelling polymeric materials, studying biological tissues and soft by: Born out of 15 years of courses and lectures on continuum mechanics, nonlinear mechanics, continuum thermodynamics, viscoelasticity, plasticity, crystal plasticity, and thermodynamic plasticity, The Mechanical and Thermodynamical Theory of Plasticity represents one of the most extensive and in-depth treatises on the mechanical and thermodynamical aspects of plastic and visicoplastic flow.

Summary A thermodynamic foundation for isothermal plasticity is laid on the basis of the hypotheses that (a) during plastic deformation the infinitesimal increment Δγ of irreversible entropy depends on the current state of stress and the stress increment and (b) that Δγ>0 for plastic deformation, whereas Δγ=0 for elastic by: 4.

The aim of the present paper is to discuss the thermodynamic approach to combined treatment of rheologic and plastic phenomena and to construct a thermodynamic theory of non-linear viscoplastic materials which may be used to describe the behavior of metals under dynamic loads.

This book has been written with the objective of bringing the concepts of elasticity and plasticity to the students in a simplified and comprehensive manner. The basic concepts, definitions, theory as well as practical applications are discussed in a clear, logical and concise manner for better understanding.

a treatment of a field as vast as plasticity theory between the covers of a truly “little” book and still hope that it will be reasonably comprehensive.

I have long felt that a modern book on the subject — one that would be useful as a primary reference and, more importantly, as a textbook in a grad.

Book Description This volume concentrates on the mathematical theory of plasticity and fracture, and presents it in a thermomechanical framework.

Many examples of plasticity and fracture are presented, and each chapter concludes with problems for s: 2. It was eventually decided to concentrate the debates on a) physical foun- dations of plasticity, b) thermodynamics of plastic and visco-plastic deform- ation, c) experiments regarding plastic behavior, d) mathematical methods in plasticity, e) computer techniques suitable for solving important techno.

The thermodynamic theory of crystal plasticity thus provides a thermodynamically consistent and physically rigorous description of dislocation motion in crystals. We also discuss new insights about the interaction of dislocations belonging to different slip systems.

The model is compatible with thermodynamics and assumes no yield or loading function, stability postulate or specific nature of the internal variables. It is shown that current theories of plasticity are restricted forms of the proposed theory.in the current presentation is still meant to be a set of lecture notes, not a text book.
