纤维缠绕复合材料壳体非线性有限元分析

Nonlinear Finite Element Analysis of Filament-Wound Case

通过数值计算，求得了纵向平面缠绕壳体的几何形状和缠绕角等，然后，利用退化壳单元对壳体进行了非线性有限元分析。

ith the numerical Calculation, the geometrical shape and winding angle etc. of the longitudinal plane for filament-wound(FW) Case are gained. And the displacement, strain and stress of the FW case are analyzea by the degenerate case element method. The results are identified with the experimental values.
