摘要
根据 Ｈｅｌｌｉｎｇｅｒ Ｒｅｉｓｓｎｅｒ 变分原理，在柱坐标系中，导出复合材料柱壳混合状态方程和边界条件的弱形式；在轴对称情况下，建立了连续闭口柱壳的热应力混合方程，给出了任意厚度连续柱壳在热荷载和机械荷载作用下的弱形式解．
Weak formulation of mixed state equations including boundary conditions of composite cylindrical shell is presented in a cylindrical coordinate system by introducing Hellinger\|Reissner variational principle, thermal stresses mixed state equation for axisymmetric problem of closed continuous cylindrical shell is established. Weak solutions are obtained for closed composite continuous cylindrical shell of arbitrary thickness under thermal and mechanical loads.
