概要

Plane strain wedge indentation of the surface of a semi-infinite porous material with a non-workhardening matrix is analysed, using an approximate method based on the slip line field theory for porous materials in consideration of the change in density during deformation. Studies are made of the influences of the wedge angle, the initial density and the yield stress of the porous material on the indentation pressure, the change in density and the mean effective strain in the plastically deforming region.
