摘要
根据断裂力学的理论和应力—强度模型,给出了在变载荷作用下,裂纹不扩展、给定寿命摘要根据断裂力学的理论和应力—强度模型,给出了在变载荷作用下,时不断裂的概率计算公式和给定可靠度时可靠寿命的计算方法。
In this paper,besed on the theory of stress-strength model and the fracture mechanics,formulas of probability calculation is presented under the affection of alternating ioad without spread of crackle and fracture in the appointed life period.Furthermore,the steps for calculation of reliable life-span with an appointeb reliability has also been given.
