An Experimental Investigation of Stresses in a Steel Model of an Overloaded Breech Ring by Means of Photoelastic Coating Technique

Abstract

An experimental investigation of stresses at the lower fillet in a two dimensional steel model of an overloaded breech ring by means of photoelastic coating technique has been made. The basis of the technique is given. Expressions for stress and strain in both the elastic and elasto-plastic state are derived. Maximum fillet stress, stress concentration factor, as well as the residual stress after unloading were found. The results were compared with previous data from polycarbonate model.
