Abstract

The continuum mechanic simulation of micro-structural damage process is important in the study of DUCTILE FRACTURE mechanics. In this paper, the CONTINUUM DAMAGE MECHANICS model formulation proposed by lematire has been validated against ductile damage evolution experimentally measured in A533B-CI steel under stress TRIAXIALITY conditions. First, a procedure to identify the model parameters from test was defined. Then, the finite element model was used simulate the experiment carried out on a notched flat rectangular bar. Good agreement was observed between the experimental results and finite element predictions. Next, the identified parameters on A533B-CI steel were used to simulate the results at necking stage and ultimate lode calculated by the damage based method were compared with those obtained from the test. The comparisons indicate a good agreement between the simulated and the experimental results.
