| Abstract: | 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. |
