Stress Singularity at the Edge Point of a Jointed Edge for Thin Plates Jointed in a Radial Pattern

Abstract

In this paper, stress singularity at a space-jointed corner of several thin plates is studied. The thin plates are jointed along a commom line and a three-dimensional corner is formed at the edge point of the intersection line. The plates are so thin that the bending rigidities are taken to be zero. The stress singularity is analyzed by using the eigenfunction expansion method. Eigenequations are given in an explicit closed-form expression for some jointed corners.
