| Abstract: | Using 2-D finite element method,authors developed an analysis program package, including tem- perature field, thermal elastic-plastic, creep, thermal fatigue and computer drawing. The low cycle thermal fatigue life of combustion chamber insert in model S195 internal combustion engine is predict- ed using this package. The common damage causes of the insert are analyzed. Some valuable design cri- teria for thermal fatigue analysis of heated parts of internal combustion engine are obtained. |
