双参数地基上层合板屈曲问题的半解析解法

摘要

Buckling analysis for uniaxially or biaxially compressed laminated plates resting on a twoparameter foundation is presented based on the classical laminated plate theory. A semianalytical approach, which makes use of DQ approximation and Galerkin method, is developed to determine the buckling loads for the plate. Numerical examples show that fiber orientation, foundation parameters, plate aspect ratio and boundary conditions have great effects on the loadcarrying capacity of the plate.%采用经典层合板理论，分析弹性地基上复合材料层合板在单向或双向受压时的屈曲特性，给出了相应的半解析计算格式.通过实际算例讨论了层合板纤维铺设角、地基参数、边界约束条件、板长宽比、弹性转动刚度等因素对其屈曲特性的影响.
