摘要
用变参数迭代法研究了弹性地基上圆板的非线性解，求得了在均布静载荷下二次近似解析解，并给出了不同弹性系数下中心挠度和载荷的特征曲线族．
A nonlinear solutions for circular plates on elastic foundations are studied by using variable parametric iteration. The second order approximate analytical solution of a plate subjected to uniform loads is obtained, and the characteristic curves of load deflection of central point with diverse foundation parameters are plotted. With the method presented in this paper, strongly nonlinear problem of a plate can be further studied.
