利用有限元分析软件MARC ，对冷却后的九层玻璃/铝阳极焊接试件进行数值模拟分析，获得了九层阳极冷却试件内残余应力和应变分布。模拟结果表明，试件冷却后各处的冷却收缩量不同，其内部存在残余应力和应变，试件发生翘曲；过渡层内的等效应力最大，且关于铝层呈对称分布；铝层内的等效应力值达到了屈服极限，表明铝层发生了塑性变形，且铝层内的等效应变最大。

After cooling ,the bonded nine-layer glass & aluminum was analyzed by finite element analysis software MARC .The residual stress and strain distributions in the bonded nine-layer glass & aluminum during cooling process were obtained . The simulation results indicate that there are residual stress and strain in the bonding due to un-uniform shrinkages ,which can cause the distortion of the bonding .The maximum value of the equivalent stress is in transition layers ,which is symmetric about the aluminum layer .The plastic deformation occurs in the aluminum layer because the equivalent stress in the aluminum layer reaches the yield stress of aluminum ,and the maximum value of equivalent strain is in aluminum layers .
