| Abstract: | finite element analysis of the viscoplastic-softening damage model is presented, in which an effective damage matrix is introduced to consider the influence of isotropic damage on different type of micro-cracking by different state of stresses. The computational techniques are improved for tracing softening deformational path of the solid with viscoplastic damage properties. Two examples are discussed to illustrate the technique for tracing the post failure path of the softening response. |
