摘要
本文对Carroll,Holt和Johnson提出的延性材料简化模型进行了改进,在模型中考虑了材料的硬化,用数值方法模拟了高速碰撞中铝板和钢板的层裂过程,其结果与实验吻合较好。
Numerical caiculations of LY12 aiumjnium and OFCH copper spallation pocesses in impact tests is carried on with Johnson's dynamic fracture model in ductile solids and consideration of material work-hardening. The compulations are in fair agreement with the experimental results.
