The law of internal stress distribution with different bt/h (tool width ratio) and different bb/h (blank width ratio) is studied. Consequently,the critical tool width ratio( bt/h )cr and blank width ratio( bb/ h )cr leading no bi-axial tension are obtained. It lays a credible foundation for designing reasonable stretching technology.展开更多
