摘要
本文基于弹塑性基本理论,针对理想弹塑性模型,随动强化模型,编制了弹塑性有限元程序,并成功地模拟了疲劳裂纹稳定扩展和超载延迟等实验现象.
Based on the classical elastic-plastic theory,an elastic-plastic finite element program is developed respectively for perfect elastic-plastic material and kinematic hardening material.It is concluded that the finite element results can simulate the stable crack growth and the fatigue crack growth retardation following overload.
