Photo-Elastic Examination of a Cylindrical Strut Intended for Recording Compressive Loads

Abstract

Photoelastic methods are used to determine the amount of stress distribution of a cylindrical steel strut 16 in. long and 6 in. diameter, mounted for measurement of compressive forces by strain gauges, even when the end load is concentrated near the axis of the strut. Results show that the strut will be in sensibly uniform stress, under axial loading, for a distance of 1-1/4 in. each side of the middle section. Consequently, constancy of the strain load factor will be achieved well within 1 percent over the middle 2-1/2 in. of the bar.
