摘要

摘要: 本文用能量法和有限差分法分析了多层复合材料圆柱壳在轴压、静水压力及扭转等载荷作用下的非线性屈曲和后屈曲性能。本文考虑了柱壳的初始缺陷、几何非线性、材料的物理非线性(剪切模量非线性)等因素对于临界载荷的影响。同时还讨论了横向剪切效应。计算分析结果与一些实验结果比较一致。

Abstract: In this paper, energy method and finite difference method are used to Compute the instability behavior ofmultilayeredfiber reinforced composite cylindrical shells under axial compression, hydrostatic pressure and torsion. The influences of initial imperfections, geometrical nonlinearities of shells and physical nonlinearities of the materials to the buckling and postbuckling behavior of the shells are considered. The effect of transverse shear is also discussed. The computational results of this paper are well agreed with the experimental data.
