Application of adaptive finite elements for solving elastic-plastic problem of SENB specimen

Abstract

The proposed adaptive finite element analysis technique without transfer of variables is used for solving elastic-plastic problem of SENB specimen. The material nonlinear problem has been solved in iterative manner from the beginning till the fixed value of loading where new adaptive FE mesh was generated. Comparison of stresses, obtained solving material and geometrical nonlinear problems with the finest FE models, has been done with solutions presented in the literature. The modelling was carried out using FE code ANSYS.
