Abstract
A parameter t is introduced to boundary slip line of rigid regions for plane strain and indirect extrusions with a fractional reduction R=0.5. Integration by substitution has been used along the boundary slip line in order to obtain the extrusion pressure. By the integration depending on a parameter, the following results are obtained,\(\bar p/2R = 1.29\) and die pressure is 5.14k for backward extrusion;\(\bar p/2R = 1.29\) and pad average pressure is 2.57k for forward extrusion. All the results from this method are the same as those of the conventional solution.
