摘要: Abstract A hardening stress strain law is determined for the AISI M2 cold forging tool steel. The experimental part based on Brinell indentation test. numerical consists in simulation of test under increasing load cases. For each case, parameters behaviour are adjusted order to make diameter converging towards one. Results compared with a rigid perfectly plastic usually used this kind Then, deformable sphere and results It shown that more accurate than one study wear tools damage since it representative reality.
