Prediction of ductile failure in tubular steel members using ABAQUS
A material failure model is implemented using the user material option in the finite element program ABAQUS, to describe ductile failure. The model uses a continuum damage mechanics (CDM) based relation to describe the dependence of the failure strain on stress state, and simulates element failure via material softening. The utility of the model in predicting the first onset of failure is demonstrated by comparing finite element predictions with experimental results taken from the literature. Experiments describing the quasi-static ductile failure of tubular steel members under a variety of different conditions have been used.
