WebPublisher's Summary Written by the leading experts in computational materials science, this handy reference concisely reviews the most important aspects of plasticity modeling: constitutive laws, phase transformations, texture methods, continuum approaches and damage mechanisms. Web1 de set. de 2024 · In this context, the finite element method faces a numerical difficulty. The discretization of the kinematics must avoid volumic locking phenomena, while ensuring the uniqueness of the approximation. Locking appears when the kinematic field unable to satisfy both the momentum balance and the plastic incompressibility equation. WebIn this paper, we propose a finite deformation theory of strain gradient plasticity. The kinematics relations (including strain gradients), equilibrium equations, and constitutive laws are expressed in the reference configuration. slushy app
