Abstract
We have analysed the development of shear bands during the perforation of a steel plate by a massive rigid punch. The contact surfaces are modeled as smooth and the steel is modeled as a thermoviscoplastic material that hardens with an increase in the plastic strain and plastic strain-rate but softens due to the rise in its temperature. The effect of punch speed, the clearance between the punch and the back supports, and the radius of the periphery of the punch nose on the development of bands is delineated.
