Numerical simulation of the process of pore collapse under shock load

ZHAO Zheng1 *,LI Xiao-jie2,TAO Gang1(1.College of Power Engineering,Nanjing University of Science & Technology,Nanjing 210094,Jiangsu,China;2.Department of Engineering Mechanics,Dalian University of Technology,The State Key Laboratory of Structural Analysis for Industrial Equipment,Dalian 116024,Liaoning,China)  
To explore the compaction mechanism of porous materials under explosive loading,the process of the circular shape pore collapse in oxygen-free copper was numerically simulated by using the LS-DYNA finite element code.Simulated results indicate that explosive welding and jet penetration can appear in the different boundary regions during pore collapse under the shock pressure of 6 GPa.These two bonding modes can improve the bonding compactness of the boundary material and enhance the density and mechanical strength of the block materials obtained by explosive compaction possess.
