Exploring Energy Discrepancies in Steel Under Static and Dynamic Loads

Abstract

The analysis of deformation energy in the plastic range for square section rods of ASTM A36 steel subjected to bending; and, in threaded rods of ASTM A193 B7 steel subjected to tension, in both cases under static and impact load tests. In the case of static loads, the AMSLER universal testing machine with a capacity of 10 tons was used to measure the applied force and the displacement from which force-displacement curves were obtained to calculate the deformation work. In the case of impact loads, the pendulum was used with the Charpy (bending) and Izod (tensile) test to directly measure the deformation energy with impact loading. The results show that the strain energy absorbed under impact loading is significantly higher than under static loading. The reasons for this discrepancy are discussed in this paper.
