A finite notched plate stiffened by a smaller circular disk (Q1094914)

In this paper, the solution of a finite notched plate stiffened by a smaller circular disk is investigated by using a partitioning plane combined with the modified generalized variational method. It is assumed that the notched plate and the disk are both under the condition of generalized plane stress. The region under consideration is then divided into three subregions and complex potentials are introduced in each subregion, whose coefficients are determined from the stationary conditions of a proposed functional. Numerical results for the effect of the disk radius on the stress concentration factors of the elliptic notch are shown in the figures. The stress distribution between the notched plate and the disk are given in a table.
