Thermodynamic Analysis of the Shock Compaction of W/Cu Granular Mixture Based on the Mesoscale Simulation

Abstract

Shock compaction is an important industrial manufacturing technology for metal powder mixture. In order to analyze the thermodynamic response of W/Cu powder mixture during the shock compaction process, numerical simulation is conducted based on the mesoscale model. The model is generated randomly according to the real morphology distribution statistics regularity. Shock wave is achieved by introduce a rigid wall moving towards the model. Therefore, effects of deformation morphology, temperature distribution and pressure distribution under different shock velocities are presented and discussed. This work could provide a detail understanding of thermodynamic response during shock compaction process in granular-level.
