Abstract
The hollow‐sphere model, with temperature‐dependent viscoplastic material response, is used to investigate thermal effects in shock compaction of metalpowders.Model calculations show very good agreement with experimental shock rise times only if the temperature dependence is considered. The results also suggest that the dynamic compaction may be qualitatively different depending on whether viscoplastic or inertial effects dominate the pore collapse process.This publication has 5 references indexed in Scilit:
