An Exact Solution for the Bending of Point-Supported Orthotropic Rectangular Thin Plates

摘要: 本文利用迭加原理,给出了点简支正交各向异性短形薄板弯曲问题的封闭的级数式解答.简支点的位置和横向载荷的分布均可任意.用本文的级数解给出的算例与以往的数值解是十分一致的.

Abstract: A closed series solution is proposed for the bending of point-supported orthotropic rectangular thin plates.The positions of support points and the distribution of transverse loadare arbitrary.If the number of simply supported points gradually increases the solution can infinitely approach to Navier's solution.For the square plate simply supported on the middle of each edge and free at each corner,the results are very close to the numerical solutions in the past.
