【摘要】 基于简单试验条件下测得的单调拉伸性能参数,同时考虑应变、温度和应力对热机械疲劳应力—应变关系的影响因素,建立了热机械疲劳应力—应变本构关系模型。试验结果表明,本文建立的模型与试验曲线相吻合。更多还原

【Abstract】 Based on the parameters of mechanical behavior under tensile and creep tests, the model of constitutive equation of stress-strain under the thermo-mechanical fatigue has been established. The test results show that the calculating values by the equation tally with the test data.更多还原
