In this paper, a nonlinear finite element modeling for the process of cross wedge rolling is presented with the aid of ANSYS/LS DYNA The reason causing concavity on the end of workpiece has been found The rule that the factor such as forming angle,spread angle,length of workpiece end and length of rolled part affect concavity has been summarized and the rule is consistent with experiment result by comparing This study is significant to properly determine the technology parameters of cross wedge rolling and increase utilization ratio of material
