Results of Photoelastic Investigation of Stresses in a Tension Bar with Unfilled Hole

Abstract

Although this problem is one which has been investigated by many photoelasticians, there appears to be no record of any systematic exploration of the effect upon the stress distribution of the ratio of hole–diameter to width of bar.In this investigation tests were made upon a standard sized bar with four different sizes of holes, and the stress distribution on the cross section of the bar through the hole centre was explored for the four cases.
