摘要
本文以附加补充项的Fourier级数作为挠度和剪力函数的模式,直接从Reissner模型建立的厚板弯曲的基本方程组出发,求解了Winkler地基上自由边矩形板的弯曲问题。文中给出了算例,并与经典薄板理论的相应解作了对比。
Fourier Series with additional terms is used as the expressions of the deflection and shear forces functions, and bending problem of thick rectangular plates with free edges on Winkler foundation has been solved, directly from the governing equations of thick plate theory developed by E.Reissner. The numerical examples have been presented and compared with the corresponding solutions of classical thin plate theory.
