文摘The stretch of blocks with rectangular section using flat anvils was simulated by using ANSYS software. The inner stress distribution for different tool width ratio w/h and blank width ratio b/h was studied. Consequent- ly, critical anvil width ratio （w/h）c and critical blank width ratio （b/h）c are obtained, which provide a sound basis for designing reasonable stretching technology.
