RESEARCH OF THE CONCENTRATION OF STRESSES IN A RECESSED PLATE USING THE METHOD OF BOUNDARY EQUATIONS
Pages 121 - 124
The subject of the research is the concentration of stresses in a plate that has two side
recesses, if the plate is exposed to the pre-set surface stress. Boundary integral equations are
derived on the basis of the reciprocity theorem. The fundamental Kelvin solution is used to define
the displacement area in the finite isotropic elastic plane. The mathematical model and the solution
algorithm, both developed by the author, represent a numerical solution designated for the plate
that has two side recesses. Comparison of results with well-known solutions demonstrates their
good convergence. The author has discovered that the smaller the radius of the recess, the higher
the stress concentration
