Void growth and coalescence modelling in AA2050 using the Rousselier model
Source abstract
Abstract
In this study, the damage evolution process in an AA2050 aluminium alloy is studied under various triaxiality levels using notched tensile specimens. The performance of the Rousselier model is assessed and it is shown that modifications are required both in the hardening curve and the damage evolution parts of the model in order to match the experimental results. The original model is corrected by adding the effect of hydrostatic pressure on the yield surface as well as implementing the Thomason coalescence model. The transferability of the Rousselier model parameters to other triaxiality levels is investigated and a procedure to identify these parameters is proposed.
