摘要:
该文基于爆轰理论,应用薄板塑性动力响应波动解及动态断裂准则,从理论上推导了薄钢板在爆炸冲击作用下产生初始环向裂纹即发生临界破坏时的装药量,给出板的临界位移理论表达式。算例、实验及仿真结果基本吻合,表明该方法能很好地解决接触爆炸载荷作用下薄板的临界破坏问题。
Abstract:
According to the detonation theory,the wave solution of plate plastic dynamic response and the dynamic fracture criterion,the critical blasting charge is theoretically derived when onset of initial circumferential crack namely critical damage happens in the thin plate under explosions.The theoretical expression of critical deformation is also obtained.The theoretical results are compared with the experimental results in the published literature and the numerical simulation results through an example.The reults are in agreement.It is shown that the method here can perfectly solve the critical damage of thin plate under contact explosions.
