摘要
以弹塑性断裂理论为基础,提出了基于J积分的疲劳裂纹扩展率工程计算方法,并推导出了D-M模型下的疲劳寿命工程计算公式.
A method for calculating the rate of fatigue\|crack growth based on J\|integral is proposed in the paper according to elasticity\|plasticity fracture mechanics. A formula for calculating the life of fatigue\|crack is also deduced upon the D\|M model. An examples is given to show that the proposed method can calculate the rate of fatigue\|crack growth.
