摘要
利用损伤力学推导了大范围损伤下的预估圆轴扭转的疲劳裂纹形成寿命的封闭解答公式,给出了确定损伤演化方程中材料常数的方法及算例。
By means of the theory for damage mechanics, closed - form solution is derived about predicting crack initiation life when torsion of a circular shaft occurs under large range damage. The method for determining material constants in damage evolution equation is given, and together with an example provided in the article.
