复合壳体 meaning in Chinese

clad shells

According to the theory of the finite element analysis , the matrix of mass , rigidity and damp in every part of shell structure have been fixed on ; at the same time , calculation has been done in dynamics and statics
利用有限元理论，分别确定了复合壳体结构中各部件的质量矩阵、刚度矩阵及阻尼矩阵，并对其进行了静力学与动力学计算，结果证明内衬三维波纹钢板复合壳体结构与普通混凝土壳体结构相比，其结构承载力有了较大的提高。
Compared with the results of the ordinary shell structure , the ribbed shell structure can improve the structural bearing capacity , so the theory of the stretching finite element analysis about statics has been extended successfully and also applied to calculation of stretching dynamics . the result indicates that the mechanics impact is of much distinctness compared with ordinary one
成功的将静力学中的弹塑性有限元理论扩展并应用于复合壳体的弹塑性动力学计算中，结果表明利用弹塑性理论计算出的结果更精确，与普通混凝土壳体的比较后可以看出，复合壳体的力学效果非常明显。
