TWO-DIMENSIONAL PHOTOELASTIC INVESTIGATION OF STRESSES IN RIFLING PROJECTIONS

Abstract

The problem of stress concentrations in rifling projections, caused by two independent simultaneous loads, is investigated experimentally using the two-dimensional photoelastic technique. A tensile field stress and a side bearing stress were applied to a series of photoelastic models and stress concentration determined for a large range of widths and fillet radii. The stress concentration factor is presented in terms of non-dimensional width, non- dimensional fillet radius and a factor relating the two loads. This presentation clearly shows the decrease in stress concentration with increasing fillet radius and width, which allows the design engineer to evaluate the trade- offs of changing fillet radius or width in establishing the shape of rifling projections.
