Series Soution for Elastic Behavior of Corrugted Circular Plates in Large Deflection under Arbitrary Loads

摘要: 本文以正交异性板理论为基础,提出了一种波纹圆板非线性弯曲的Chebyshev级数解法,推导出具有中心平台的波纹圆板在任意轴对称载荷作用下的弹性特征方程.文中计算了几个典型的特例,数值结果表明,本文的方法对目前常用的方法有一定的改进和推广.

Abstract: Chebyshev polynomials are used to solve the problem of large deflection for corrugated circular plates with a plane central region under arbitrary loads based on the nonlinear bending theory of anisotropic circular plates. Numerical results are compared with those available in the literature. The present method shows higher accuracies and larger application ranges.
