Photoelastic Study of the Stresses of the Cantilever with a Semi-circular Notch

Abstract

The stresses of the cantilever with a semi-circular notch have been investigated photoelastically. In the experiments, the test pieces are made of KT-102 (epoxy resin), having 4 types of semi-circular notch. Consequently, under the condition of cantilever, the maximum stress developed at the boundary of the notch is a function of the 3 parameters, namely, the radius of the semi-circular notch, the distance of the loading point from the clamped end, and the distance of clamped end to center of the semi-circular notch. The stress concentration of pure bending is applied to the cantilever, having same notch, in some range.
