Modelling damage of AlZnMg alloys

The present work is concerned with the modelling of damage initiation and growth in AlZnMg alloys, and also with an estimation of the ductility in uniaxial tension. An elastoplastic self-consistent model is developed accounting for crystallographic texture and grain shape effects, which also integrates the voids formed by the damage process. The damage evolution is followed within this framework, allowing the prediction of the macroscopic …
