Effects of anisotropic yield criteria on the prediction of wrinkle during the deep-drawing forming of aluminum alloy sheet

The effects of different anisotropic yield criteria(Hill1948,Barlat YLD91 and CMTP) on the deep drawing simulation of a circular blank sheet based on FEM were studied,and the numerical solution of different yield functions was compared with each other.The results show that stress distribution is different by using these three yield criteria,the wrinkle is higher for Barlat's YLD91 and CMTP's than for Hill's(1948).
