Iso-Damage Curves for a Simply Supported Beam.
Abstract
The paper presents a theoretical development of iso-damage curves for elastic-perfectly plastic simply supported beams which are loaded by blast waves. A blast wave is modeled as a simple exponentially decaying forcing function. The development assumes the beam responds in its normal modes of vibration during the elastic phase of the response and as a mechanism after the elastic limit is reached. The use of iso-damage curves is illustrated. Theoretical predictions of plastic deformation of a simply supported beam computed using the first mode approximation and those computed using the first and the third mode approximation bracket the experimental data of Baker.
