Experiments on Large Plastic Deformations of Circular Plates with Work Hardening

Abstract

Tests were performed on three simply supported circular plates of aluminum alloy 2024-0, under a central concentrated load, with large deflection. The load was provided by a small diameter hard steel rod. Measurements were made of load, deflections, and strains, and membrane and bending strains were calculated from the test data. Twenty electrically bonded strain gauges were used to measure the distribution of radial and circumferential strain components along a radial line on both faces of each plate. The test data are presented in comparison with theoretical predictions generated by the Grumman-developed finite element computer code PLANS.
