2012 (English)In: Nonlinear Acoustics: State-Of-The-Art And Perspectives (ISNA 19) / [ed] Kamakura, T; Sugimoto, N, American Institute of Physics (AIP), 2012, 172-175 p.Conference paper (Refereed)
Non-linear elasto-plastic shock waves in particle systems at high-velocity compaction are simulated by the discrete element method. The contact laws applied between the spherical metal particles include non-linear elastic and plastic loading, adhesion and elastic unloading. Of particular interest is to study the transmission and reflection of non-linear shock waves through a particle system with and without voids between the particles. Interesting results are presented in the paper including the particle deformation at incident and reflected shocks and particle velocity oscillations as a result of voids. The study of non-linear elasto-plastic shock waves in particle systems has a strong practical relevance including high-velocity compaction of metal powder.
