Title
Densification of Sintered Porous Metal under Hydrostatic Pressure
김형섭Hyoung Seop Kim, 이동녕Dong Nyung Lee
Abstract
Density distributions of sintered porous metal with various initial densities during hydrostatic compaction have been calculated using a proposed yield function. The calculation was performed using the iteration method. The caculated results were in very good agreement with experimental ones. The geometric hardening and material strain hardening of the metal were found to have an important effect on the porosity-pressure relation.
