摘要: 本文在前文[1]、[2]所得的微分方程和有关边界条件的基础上.采用一种新的整体插值法,求得了弹性圆板在一侧受均载而四周固定的条件下弯曲问题的不用克希霍夫-拉夫假设的一级近似理论的数值结果,并与经典的克希霍夫-拉夫理论[3]和Reissner修正理论[4,5]的结果进行了比较.

Abstract: Based upon the differential equations and their related boundary conditions givenin the previous papers[1,2],using a global interpolation method,this paper presents anumerical solution to the axisymmetric bending problem of non-Kirchhoff-Love theoryfor circular plate with fixed boundary under uniform surface loading.All the numericalresults obtained in this paper are compared with that of Kirchhoff-Love classicaltheory[3] and E.Reissner's modified theory[4]-
