Experiments on Wedge Indentation of a Porous Material : Indentation Hardness of a Porous Material : 2nd Report

概要

論文の詳細を見る
Experiments on the wedge indentation of a porous material are carried out using workhardened and annealed specimens of sintered copper powder. Studies are made on influences of the initial relative density, the wedge angle and the frictional condition on the indentation pressure. The indentation pressure is compared with the flow stress obtained from tests of plane strain compression of sintered copper powder. The deformation pattern is also obtained by means of the grid method.
