【摘要】 本文利用广义富里叶级数法对非对称复合材料层板在面内载荷作用下的非线性横向变形或屈曲问题进行了分析。文中主要研究了四边简支边界条件下,非对称层板的铺层方式和面内载荷形式对横向变形的影响。通过求解非线性控制方程得到了层板的载荷—挠度曲线或特殊情况下的后屈曲平衡曲线。计算结果表明,对于大多数非对称复合材料层板在面内载荷作用下所产生的是横向变形问题,而不是分叉屈曲问题。更多还原

【Abstract】 In this paper, the nonlinear transverse deflection or buckling is analyzed for unsymmetrical composite laminates under loads in plane by means of the generalized Fourier series method. The influences are studied mainly of the layout of unsymmetrical laminates and the type of loads in plane on the transverse deflection of composite laminates supported simply at four edges. The curves of load-transverse deflection or the curves of postbuckling equilibrium in special case of composite laminates are obta-ined by solving the nonlinear governing equations The numerical results. show that the unsymmetrical composite laminates under loads in plane generally produce only transverse deflection, but not buckling更多还原
