Com uter Science Section, Shenyang Artillery College, Shenyang110162, China) AbstractNumerical analysis for 0 1Al/ SiC laminated composite mat erial under cycling tempera- . , ture load has been done in this paper Structural element in ANSYS soft ware was used w hile Al was consid- ered as elastic-plastic model and Mises kinematic plast ic t heory w as introduced. Temperat ure-dependent ma- terial properties w ere used.The residual plastic deformat ion and thermal stress w ere calculated, and t he cy- cling residual thermal st ress curve form 205 to 20 temperature cycle w as obtained.The analytical results are in good agreement w it h its experim ent al data.The research in this paper could provide good theoretical basis to t he prediction of its therm al fat igue life. Key wordscomposite material; residual thermal st ress;finite element analysis
