WEIGHTED RESIDUAL SOLUSION ON LARGE DEFLECTION NONLINEAR PROBLEM OF LAMINATED COMPOSITE SHALLOW SHELLS AND PLATES

本文在文献［１］的基础上，用加权残数法分析了复合材料多层板壳大挠度非线性问题。文中推导了相应的关系式，分析了复合材料多层矩形扁壳，与小挠度线性理论解析解进行了对比。结果表明，分析复合材料多层板壳大挠度非线性问题时，加公残数法是有效的。

Based reference,in this paper we have applied weighted residual method to analysis of large deflection nonlinear problem of laminated composite shallow shells and lates. We have derived the relative formulas and analyzed the rectangular laminated composite shallow shells .The results have been compared with the small deflection linear analytical solution. The results proved that weighted residual method is effective on analysis of large deflection nonlinear problem of laminated composite shallow shells and plates.
