摘要 通过选择恰当的模型和科学的空间离散化,对SHPB加载过程进行了2D数值模拟,数值重现了帽型试样高应变条件下的绝热剪切变形历程。基于应力塌陷绝热剪切形成判据分析了材料绝热剪切变形规律;利用模拟结果的应力-时间、应变-时间曲线进行了温度场的计算,确定了剪切带的类型,计算结果与实验结果吻合。  Appropriate model and space discretization were chosen to simulate the loading process of specimens conducted on the Split Hopkinson Pressure Bar(SHPB) in two-dimension,and the adiabatic shear deformation course of the hat-shaped specimen under high strain rate was obtained.Based on the criterion of the formation of adiabatic shear to Stress Collage,the rule of adiabatic shear deformation was analyzed,the simulated stress-time curves and strain-time curves were employed to calculate the temperature field,the type of the shear bands was determined,and the results of numerical simulation are consistent with the experimental results.
