In this comprehensive , we will delve into the foundations of this fascinating field, exploring its applications, challenges, and the remarkable insights it offers into the behavior of materials under stress.

Unveiling the Concept of Computational Plasticity

Computational plasticity is a subfield of computational mechanics that focuses on accurately modeling and predicting the deformation and failure of materials subjected to mechanical forces. Traditionally, plasticity theory studied the behavior of materials without relying on computers. However, the rise of computational power and advanced numerical algorithms has revolutionized this field, offering researchers powerful tools to simulate and analyze complex processes with unprecedented accuracy.

While plasticity itself refers to the ability of materials to undergo permanent deformation without fracturing, computational plasticity magnifies our comprehension of this phenomenon. By employing advanced mathematical models and numerical simulations, researchers are now able to investigate how different materials, such as metals, polymers, or composites, respond to various loading conditions, providing valuable insights into their mechanical properties.

This book gives an to computational plasticity and includes the kinematics of large deformations, together with relevant continuum mechanics. Central to the book is its focus on computational plasticity, and we cover an to the finite element method which includes both quasi-static and dynamic problems. We then go on to describe explicit and implicit implementations of plasticity models in to finite element software. Throughout the book, we
describe the general, multiaxial form of the theory but uniquely, wherever possible, reduce the equations to their simplest, uniaxial form to develop understanding of the general theory and, we hope, physical insight. We provide several examples of implicit and explicit implementations of von Mises
time-independent and visco-plasticity in to the commercial code ABAQUS (including the fortran coding),which should prove invaluable to research students and practising engineers developing ABAQUS 'UMATs'. The book bridges the gap between undergraduate material on plasticity and existing advanced texts on nonlinear computational mechanics, which makes it ideal for students and practising engineers alike. It introduces a range of engineering applications, including superplasticity, porous
plasticity, cyclic plasticity and thermo-mechanical fatigue, to emphasize the subject's relevance and importance.
