The spallation experiments of Al-Li alloy have been carried out and the free surface velocity temporal curves for the spallation events have been measured. Based on the microscopics statistics and phenomenological analysis, a damage evolution equation is developed, which involves the effects of the growth and nucleation of microcavities as well as the effects of the material's compressibility. Inserting the constitutive equation and Murnagham state equation of Al-Li alloy and the damage evolution equation into ANWP, which is a special program for one-dimension strain wave, and by the numerical simulation of the free-surface velocity temporal curve for the spallation events in the gas gun experiments, we have obtained the related parameters in the damage evolution equation and the spallation criterion.

通过平板撞击实验对铝锂合金层裂现象进行实验研究。以细观统计和唯象分析相结合的思想,提出了一种新的微孔洞型损伤演化方程,方程同时计及了孔洞长大、成核以及材料可压缩性的耦合效应对损伤演化的影响。在一维应变波模拟程序中嵌入考虑损伤演化影响的铝锂合金本构方程和状态方程,模拟平板撞击过程靶板自由面质点速度时程曲线,并与实验曲线相对比,得到了铝锂合金材料损伤演化方程及其层裂准则的相关参数。

通过平板撞击实验对铝锂合金层裂现象进行实验研究。以细观统计和唯象分析相结合的思想,提出了一种新的微孔洞型损伤演化方程,方程同时计及了孔洞长大、成核以及材料可压缩性的耦合效应对损伤演化的影响。在一维应变波模拟程序中嵌入考虑损伤演化影响的铝锂合金本构方程和状态方程,模拟平板撞击过程靶板自由面质点速度时程曲线,并与实验曲线相对比,得到了铝锂合金材料损伤演化方程及其层裂准则的相关参数。

铝锂合金  /  损伤演化  /  层裂准则  /  数值模拟

The spallation experiments of Al-Li alloy have been carried out and the free surface velocity temporal curves for the spallation events have been measured. Based on the microscopics statistics and phenomenological analysis, a damage evolution equation is developed, which involves the effects of the growth and nucleation of microcavities as well as the effects of the material's compressibility. Inserting the constitutive equation and Murnagham state equation of Al-Li alloy and the damage evolution equation into ANWP, which is a special program for one-dimension strain wave, and by the numerical simulation of the free-surface velocity temporal curve for the spallation events in the gas gun experiments, we have obtained the related parameters in the damage evolution equation and the spallation criterion.
