摘要
本文提出将摄动法和积分方程法联合应用,直接对Pasternak弹性地基上薄圆板的Karman型非线性基本微分方程进行求解。分析了弹性地基上周边固定薄园板在中心集中力作用下的大挠度弯曲问题。研究表明,这一方法简明、计算量小,且结果合理、可靠。
Based on Karman's nonlinear foundamental differential equations, the new method combines perturbation method with integral equation method is forward to solve nonlinear bending of a clamped circular plate on Pasternak foundation under a concentrated load at the center. This method is simple and easy to use. The numerical results show that the present solution is reliable.
