Abstract

This paper deals with plane strain indentation of annealed brass by both symmetric and half wedges, and the connection between wedge indentation and incipient chip formation by a positive rake angle tool. Indentation forces and wedge-plate contact lengths were measured, and plastic deformation underneath the indenters was studied by microhardness scanning and discussed. Half-wedge indentations at decreasing distances from the plate corner were shown to result in a transition from wedge indentation to chip formation. © 1977 by ASME.
