Photoelastic Investigation on Stresses of I-Beam with a Hole under Tension

Abstract

The object of the work described was to obtain information about the stresses due to tension in an I-beam with a circular hole at the web, which were studied photoelastically. Test pieces were made of epoxy resin with adhesive method. The stress concentration occurred on the hole boundary at the minimum section. The values of stress concentration of the I-beam were calculated from the values of the stress concentration with a circular hole of a beam having the equal sectional area without a flange.
