Integral Formulation of Coupled Damage and Viscoplastic Constitutive Equations: Formulation and Computational Issues
Source abstract
Abstract
In this paper, well-known differential elasto-viscoplastic constitutive equations, accounting for hardening and damage, are reformulated into integral form in order to propose an efficient implicit integration scheme. By working out some examples, it will be shown that the proposed formulation appears to be computationally more appealing in terms of numerical accuracy and CPU time.
