Numerical analysis of anisotropic ductile continuum damage

The paper deals with the numerical analysis of large elastic-plastic deformation behavior of anisotropically damaged ductile solids based on a generalized macroscopic theory within the framework of nonlinear continuum damage mechanics. Estimates of the stress and strain histories are obtained from a straightforward numerical integration algorithm based on operator split methodology which employs an inelastic (damage plastic) predictor followed by an elastic corrector step. The finite element method is used to approximate the linearized variational problem. Furthermore, identification of material parameters is discussed. Numerical simulation of the elastic-plastic deformation behavior of damaged tension specimens demonstrate the efficiency of the formulation. (C) 2003 Elsevier B.V. All rights reserved.
