Dynamic deformation of al under shock loading
WebNov 29, 2024 · Firstly, after the spread of shock wave, the cavity is densely filled by the flow deformation of the Al particles. Then, the Ni and Al particles are tightly joined together at the atomic scale by the produced high pressure and temperature. The exothermic reaction in the compressed particles is because the Ni atoms diffuse into the Al phase. WebMay 17, 2024 · Spallation is a typical dynamic fracture mode under shock loading and has attracted the attention of most researchers. However, due to the difficulty in measuring temperature in dynamic experiments, the effect of initial temperature on spalling response has been rarely investigated.
