摘要

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. Consequently, 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.
