基于均匀化理论研究了复合材料粘弹性分析的多尺度方法，以及复合材料等效热应力松弛规律。
Based on the homogenization theory, the multi-scale analysis methods of the viscoelastic property, and the effective thermal stress relaxation laws are studied.
结果表明：加工以后使应力重新分布和使残余应力降低或均匀化，冷热循环去应力处理效果很小。
The results indicated that after machining the stress is re arranged and the residual stress decreases; the effect of thermal cycle stress relief treatment is little.
利用数值方法研究材料空洞化和承受应力沿板厚分布的非均匀性对材料分叉（平板中平面剪切带和表面皱曲）的作用。
