How do I obtain these ductile damage parameters(initiation and evolution) to apply in abaqus in order to have damage criteria. I have experimental data form a steel device that is subjected to a hysteresis loop. So I can get the dissipative energy from the area of the force displacement graph. But i can't find a solution to apply these parameters in order to simulate the damage criteria. Do you think ductile damage is a good application for this example or should I do other damage criteria and how do I get the parameters for that damage criteria? Thank you.
Diogo Cabrita sir, while calculating the fracture energy, do we have to consider the stress vs strain graph, where strain is in (%) or do we have to convert it to the original strain by dividing it by 100
