摘要
在分析温度、相变、应力的相互耦合关系的基础上,讨论了相变条件的数学模型和相应材料性能改变的方程,提出了反映相变影响的温度场控制方程,导出了含相变的热弹塑性本构方程,应用有限元进行了温度场。
Based on the analysis of coupling action of temperature,phase transformation and stress,the phase transformation condition and equation related to materials properties are discussed.The expression showing the temperature field effecting on phase transformation and the thermal elastoplastic constitutive equation are derived.Finally,the analyses of temperature field and stress field are made by finite element method.
