Utilization of the Bend Test for Determining Stress-Strain Curves

Abstract

Experimental verification of the utilization of the bend test for determining stress-strain curves for tension and compression is presented. Stress-strain curves are determined from independently performed tension, compression, and bend tests of AISI 4340 steel specimens (heat treated to three nominal yield strength levels - 125,000, 175,000, and 225,000 psi, respectively, at 0.2% offset) and compared. Fair agreement is found to exist among the curves up to the 2% strain limit of each test.
