About this document
Lemaitre-Chaboche Viscoplastic Model by sameer Shah is a document available to read on EtoBox.
The document describes a Lemaitre-Chaboche viscoplastic model that combines isotropic and kinematic hardening to model effects like ratcheting, cyclic softening/hardening, and stress relaxation in metals under high-temperature cyclic loading. It presents the governing equations, material parameters for an indium alloy, and results of simulations showing stress-strain behavior under different loading conditions such as symmetric vs non-symmetric strain/stress cycles. The COMSOL implementation uses von Mises
