摘要
基于复合材料各向异性板的大挠度方程,采用Ritz法和最小势能原理推导出了正交各向异性复合材料层合板在面内弯曲载荷作用下临界屈曲弯矩的解析解;给出了面内弯剪复合载荷作用下复合材料层合板屈曲的强度校核方法,并将本文方法所得结果与用有限元法(FEM)所得结果进行了比较。结果表明,本文方法与有限元方法相吻合,并且形式简洁,便于工程应用。
Based upon the large deflection equation of anisotropic composite panels, an analytical method for the buckling under in-plane bending load of orthotropic composite laminates has been presented by utilizing Ritz method and the principle of minimum potential energy. Moreover, a stress analysis method for the buckling of composite laminates under bending shear combination loads was presented as well. The result by the present method was compared with that by the finite element method （FEM）. The result by both the present method and FEM agree very well. The expression for the present method is clear and concise, which is easy to be applied in engineering practices.
