Abstract
In this paper the Rousselier ductile damage model is used to simulate the softening behaviour of notched bars and crack growth in a pre-crac ked specimen of an A508 pressure vessel steel. The effect of the inter nal parameters needed to represent the damage on the calculated result s is studied. The interactions between these parameters and their effe cts on the calibration process are discussed. The effect of the cell s ize on the values of the damage parameters obtained during calibration and on the response of the specimens is briefly reviewed.
