Photoelastic Investigation of the Stresses in Mitred Bent-cylinders Under Bending II : For Various Bent-angles

Abstract

The states of stress distribution in mitred bend subjected to in-plane uniform bending moment have been studied systematically by means of photoelastic stress freezing method. The relations between the stress concentration factor of fiber stress σ_l and of hoop stress σ_θ near the bent art and the angle of mitred bend are thoroughly investigated. The effects of fillet radius of the bent-part and wall thickness on the stress concentration factors are also discussed.
