Finite element prediction of fracture occurring in tensile test of a cylindrical specimen

摘要：

In this paper, finite element prediction of a tensile test of a mild steel is conducted with emphasis on fracture prediction. A rigid-plastic finite element method is used. Brozzo damage model is used to find damaged elements. The node splitting technique is used to generate the crack onto the damaged elements. The flow stress obtained by an iterative method of material identification is employed, which makes it possible to predict the tensile test up to the fracture point exactly in the engineering sense. The approach is successfully applied to predicting the entire tensile test of a cylindrical specimen with emphasis on fracture prediction. The comparison of the tensile load-elongation curve between the predictions and experiments shows a good agreement
