Abstract

The numerical analysis of microdamage evolution in S235JR steel is presented in the paper. The simulation was performed basing on the Gurson-Tvergaard-Needleman material model which takes into consideration the influence of microdamage to the material strength. The plate element with a central hole was considered. It modelled the structure discontinuity which may occur in structural element due to such a phenomenon as corrosion. The numerical simulation and analysis of micro-damage evolution for this element made of S235JR steel was carried out, which allowed to show and detect the micro-crack initiation and area subjected to final failure.
