    • To generate a combined model for isothermal and anisothermal fatigue life of a material, multiple strain-controlled fatigue tests are performed on the material. For each test, test data is generated that includes a normalized load and a number of cycles to occurrence of crack initiation in the material under a normalized load which is a function of multiple instantaneous load levels determined at different points in time during the test. Each individual instantaneous load level is determined by normalizing a measured stress at an instant with a value of a temperature dependent property of the material corresponding to a temperature of the test at that instant. The test data from the plurality of strain-controlled tests are processed to generate a combined lifetime model defining a response of the number of cycles to occurrence of crack initiation to the normalized load.
    • 为了产生材料的等温和各向异性疲劳寿命的组合模型,对材料进行多个应变控制疲劳试验。 对于每个测试,产生测试数据,该测试数据包括标准化负载和在归一化负载下在材料中发生裂纹发生的循环次数,其是在测试期间在不同时间点确定的多个瞬时负载水平的函数。 每个单独的瞬时负载水平通过在瞬间将测量的应力归一化为与该时刻的测试温度相对应的材料的温度依赖性的值来确定。 来自多个应变控制测试的测试数据被处理以产生组合寿命模型,该模型定义了对归一化负载产生裂纹发生的周期数的响应。
