摘要
采用有限元程序分析了平板表面裂纹在循环载荷作用下的应力 应变场的变化情况,找出了气瓶裂纹承受各种不同过载条件时力学量的改变规律,从而验证了试验研究工作的结果·
The stress-stain field of the surface crack on a plate under circular loads is analyzed using finite element method. Finds out the influence rule of the mechanics parameters of the cracks under different over-load conditions. The experimental results is approved.
