本文提出了一种新的分析方法，用于预测由具有不同拉伸和压缩性能的层组成的层压板的机械行为。作为案例研究，考虑了简支、多层、不对称、特殊正交各向异性层压板在各种类型的横向载荷下的弯曲。使用的基础弯曲理论是高阶剪切变形理论。利用所提出的方法，可以分析具有多于两层的层压板，而不必采用反对称堆叠顺序。通过将其结果与其他更简单的理论的结果进行比较，证实了新方法的有效性。最后，作为一个例子，计算五层、不对称、特殊正交各向异性层压板的挠度、应变和应力。
A new analytical method for the prediction of the mechanical behaviour of laminates consisting of layers having different properties in tension and compression is proposed in this paper. As a case study, bending of simply supported, multilayered, unsymmetric, specially orthotropic laminates under various types of lateral loads is considered. The underlying bending theory used is a higher-order shear deformation theory. With the proposed method, laminates having more than two layers, not necessarily in an antisymmetric stacking sequence, can be analyzed. The validity of the new method is confirmed by comparing its results with the ones of other simpler theories. Finally, as an example, deflections, strains and stresses are calculated for a five-layer, unsymmetric, specially-orthotropic laminate.
