Abstract :
A numerical simulation based on the pressure-sensitive yield criterion of Gurson mesomechanics model is presented for explicit dynamic finite element calculations of SS304 bar under tension at high rates of strain. The necking process, including void nucleation and coalescence, is modeled numerically. The result shows clearly the crack propagation and eventual separation. The numerical analysis is compared with the test, and they are agreeable by macroscopic concept.
