摘要
从概率断裂力学与概率损伤容限分析的关系出发,确定了能够应用概率损伤容限设计的飞机与发动机疲劳关键结构,给出了应用概率断裂力学得出的从初始裂纹到临界裂纹疲劳循环总数计算公式。
Base on the connection of fracture probability and damnification tolerance, confirm the key structure of airplane and engine can apply the theory of damnifcation tolerance probability designed. Apply the theory of fracture probability, advanced the calculational expressions to calculate total cycle from preliminary to critical crackle.
