| 摘 要： | 本文讨论计及横向压力作用时,正交异性复合矩形板在面内双向压缩作用下的后屈曲性态.从正交异性复合板Karman 型大挠度方程出发,先用GALERKIN法将横向压力作用转化为初挠度影响,然后以挠度为摄动参数,采用摄动法,导得正交异性复合矩形板屈曲载荷关系曲线及后屈曲平衡路径.计算结果表明,有横向压力作用与无横向压力作用时,载荷关系曲线及后屈曲平衡路径都有明显差别.

| Abstract: | Postbuckling behavior of orthotropic rectangular plates underbiaxial compression combined with lateral pressure is considered.Based on the von Karman-type nonlinear large deflection equations oforthotropic rectangular plates,the lateral pressure is first converted into aninitial deflection with the GALERKIN method,and then the postbucklingbehavior of simply supported orthotropic rectangular plates under biaxialcompression combined with lateral pressure is studied by using the perturb-ation method with deflection as its perturbation parameter It has been foundthat there exists evident discrepancy between the case with lateral pressureand that without lateral pressure. |
