Iterative Method on Large Deflection Nonlinear Problem of Laminated Composite Shallow Shells and Plates

Department of Civil Engineering, Southwest Institute of Technology, Mianyang, Sichuan 621000, P R China

摘要: 在王震鸣等人提出的各向异性多层扁壳的大挠度方程的基础上,提出了复合材料多层板壳大挠度非线性问题的迭代解法。分析了四边简支的复合材料多层矩形扁壳,与小挠度线性理论解析解及有限元非线性解进行了对比。结果表明,载荷较小并发生小挠度时,所得的大挠度解和小挠度解析解非常接近,载荷较大时,所得解和有限元非线性解非常接近。

Abstract: Based on result by Wang,in this paper the iterative method is presented for the research of large deflection nonlinear problem of laminated composite shallow shells and plates.The rectangular laminated composite shallow shells have been analyzed.The results have been compared with the small deflection linear analytical solution and finite element nonlinear solution.The results proved that the solution coincide with small deflection linear analytical solution in the condition of a little loads and finite element nonlinear solution in the condition of large loads.
