Iso-Damage Curves for Plates Under Blast Loading.
Abstract
The report presents a development of iso-damage curves for a fixed edge square membrane, a simply supported circular plate, a clamped circular plate, a simply supported square plate, and a clamped square plate. The blast loading of the membrane is idealized two ways; first as a rectangular pressure pulse and secondly as an exponentially decaying pressure pulse. The blast loading on the plates is idealized as a rectangular pressure pulse. The membrane is assumed to behave like rigid-plastic material that will not deform until the yield stress is reached. Expressions are obtained for the final deflection of the membrane and by the judicious choice of dimensionless variables, a single iso-damage curve is developed. (Modified author abstract)
