Numerical analysis and modeling of large deformation and necking behavior of tensile specimens

The present paper is concerned with numerical simulations of large deformation and necking behavior of axisymmetric tensile specimens. In particular, an efficient framework for the numerical analysis of finite deformation behavior of elastic-rate-independent plastic problems is summarized which is based on a plastic predictor method. Furthermore, numerical modeling of conventional tensile tests as well as their finite deformation and localization phenomena are discussed in some detail, and the results will be compared to those obtained by simplified numerical simulations.
