Discussion on“Rectangular Plates with Free Edges on Elastic Foundations”

This paper points out the former work does not fulfill the boundaryconditions that the concentrated force at the four corner points should notexist.Therefore,Ritz method adopted by the author concerned in the illus-trative example will not be convergent in the best way.Moreover,Garlerkinmethod which is illustrated in this paper may carry out incorrect results ifwe apply its formulae.We have proved that the boundary conditions whichgovern the concentrated force equal to zero at the four corner points areindispensable if the problem is properly set.     

“对弹性地基上的自由边矩形板”的探讨

本文指出:文献[1]不满足板的四个角点集中反力为零的边界条件,所以[1]采用黎兹法给出的算例,其近似解的收敛性不是最妙的[1]又给出了用迦辽金法计算的公式,如果沿用其公式将导致错误的结果.本文证明了四角点集中反力为零的边界条件是必要的一个定解条件.     

Discussion on “Rectangular Plates with Free Edges on Elastic Foundations”

This paper points out the former work does not fulfill the boundary conditions that the concentrated force at the four corner points should not exist. Therefore, Ritz method adopted by the author concerned in the illustrative example will not be convergent in the best way. Moreover, Garlerkin method which is illustrated in this paper may carry out incorrect results if we apply its formulae. We have proved that the boundary conditions which govern the concentrated force equal to zero at the four corner points are indispensable if the problem is properly set.
