Abstract:

 Understanding dynamic behavior of steel has gathered the efforts of many researchers during the last decades. Steel AISI 304 is the most widely used stainless steel. It has excellent forming and welding characteristics, extensively used in a variety of industries. Numerical modeling is often used in experimental investigations as full scale tests are expensive and may be impossible to conduct correctly. This is especially true for high and wide range of strain-rate events such as dynamic tensile. In this work the damage viscoplastic behavior of steel AISI 304 will be microscopically modeled using the Abed-voyadjis model (physic model based on the thermal activation of dislocation) combined with the BONORA and BAI (lode angle criterion) damage criterion. These models will be implemented in Abaqus / Explicit, we used the VUMAT (Vector zed User MATeriel) user subroutine and radial return mapping algorithm to solve incremental problems. Finally, we realize numerical simulations in Abaqus/Explicit for different rate strain on the tensile specimens (flat), and we compare numerical results obtained by our model with the experimental results.
