针对弹性地基上四边自由中厚板弯曲问题由于数学模型复杂而难以求解的问题,提出了一种双重有限积分变换法,求解了四边自由中厚板弯曲的解析解。通过文献和有限元计算,验证了该方法的准确性。本文提出的求解方法可用于求解具有不同边界条件的板的问题,而无需预先确定任何试解。本文所得结果可作为今后研究的基准。
Double finite integral transform method is proposed in this paper to obtain the analytical bending solutions of moderately thick rectangular plates with all edges free resting on elastic foundations, which was difficult to be acquired due to the complexity of the mathematical model. The accuracy of the method is validated by the literature as well as the finite element method (FEM). The solution approach presented here can be used to solve the problems of plates with different boundary conditions in an elegant, step-by-step way without predetermining any trial solutions. The results obtained in this paper can serve as benchmarks for future reference.
