A thermo-visco-plastic constitutive relation for the metal, which can cover plastic hardening (softening) behaviors, thermo-softening behaviors and damage-softening behaviors, is adopted in the numerical computation for analyzing the metal spallation induced by laser. Computations are carried out in one-dimensional and two-dimensional cases, respectively. Attenuation of shock wave pressure is calculated, as well. The calculated spallation thickness is in good agreement with the experimental observations.

通过简化的物理分析,将脉冲激光加载简化为一定的力学边界条件,考虑了材料内部的损伤演化,采用含损伤的热粘塑性本构模型模拟了铝合金材料的层裂。由于脉冲激光产生的压力脉冲较短,随后的卸载波将使得靶中传播的冲击波压力幅值下降。一维和二维计算得到的层裂片厚度与已有的实验数据符合很好。通过计算,得到了脉冲激光发生层裂时的应变率。

通过简化的物理分析,将脉冲激光加载简化为一定的力学边界条件,考虑了材料内部的损伤演化,采用含损伤的热粘塑性本构模型模拟了铝合金材料的层裂。由于脉冲激光产生的压力脉冲较短,随后的卸载波将使得靶中传播的冲击波压力幅值下降。一维和二维计算得到的层裂片厚度与已有的实验数据符合很好。通过计算,得到了脉冲激光发生层裂时的应变率。

激光  /  层裂  /  热粘塑性本构  /  损伤

A thermo-visco-plastic constitutive relation for the metal, which can cover plastic hardening (softening) behaviors, thermo-softening behaviors and damage-softening behaviors, is adopted in the numerical computation for analyzing the metal spallation induced by laser. Computations are carried out in one-dimensional and two-dimensional cases, respectively. Attenuation of shock wave pressure is calculated, as well. The calculated spallation thickness is in good agreement with the experimental observations.
