该模型提供一种新的测定材料和结构应力（载荷）寿命曲线的简易方法。 - The existed material fatigue performance test curves are dealt with and analyzed , and the non - dimensional stress - strain curve , tangent modulus factor curve and fatigue life curve are drawn based on the experiment data , and these three non - dimensional parameter curves are used to find the inherent rules that the test curves can be replaced each other to some extent . it can be concluded that if the common character and system error of these materials are found , the test curve of a certain material can be used for reference by another material . this is a simple approach about fatigue life estimate and is engineering practical
对已有的材料力学疲劳性能试验曲线进行分析整理，利用试验数据绘制了相对应力应变曲线、切线模量因子曲线和疲劳寿命曲线，利用这三种无量纲参数曲线发现了其中存在的规律性，即在某种程度上实验曲线可以互相取代，并用试验数据对此进行了讨论，并由此推断，如果找出材料彼此的共性或彼此之间的系统误差就可以将一种材料的试验曲线供其它材料参考使用，这是一种估算材料的疲劳寿命的简便方法，对工程而言具有实用性。 - Based on the experimental data of rotor steel 1crmov in the loading of low - cycle fatigue at high temperature , the strength behavior and the fatigue life curve of this material at 550 have been achieved . meanwhile , with respect to three kinds of notched bar , their material damage assessment method under multiaxial stress condition is discussed
