Numerical Analysis of High Explosive-Induced Multiple Layers in Sn Metal
摘要
Abstract
After validating our hydrodynamics program and damage model with the corresponding experimental data,we carried out numerical simulation study on the damage and spall mechanism of Sn under the explosive detonation loading.The numerical results show that the damage in Sn sample is related to the loading intensity,the wave profile and the sample size;the initial microstructure of the material will act on the critical fracture damage and then affect the damage and spall in the sample,and the damage decreases with the increase of the critical fracture damage.Moreover,the comparison of the numerical results with the experimental results on the tension and compression damages indicates that the tension damage plays a decisive role in material damage.关键词
