当用应力—强度干涉理论计算断裂概率,问题归结为一维积分式的求解。
And then, by using the stress strength interference theory to calculate fracture probability is converted to resolve a one dimensional integral.
他将风力公式应用到他的模型中,并假定树枝受到风力作用而断裂的概率是恒定不变的,据此他推导出了达·芬奇公式。
When he plugged that wind-force equation into his model and assumed that the probability of a branch breaking due to wind stress is constant, he came up with Leonardo's rule.
最后,应用概率断裂力学方法(PFMA),对含初始裂纹体的直升机金属材料(铝合金)构件的疲劳裂纹扩展寿命进行可靠性分析。
Finally, applying Probabilistic Fracture Mechanics Approach (PFMA), the reliability analysis is carried out for helicopter metal material (aluminum alloy) structure having initial cracks.
