Abstract
The plastic response of clamped mild steel, copper, and aluminum circular plates, subjected to blast loads is investigated by experimental and analytical methods. Extensive experimental results concerning, variations of central deflection are presented. The effects of plate thickness, standoff distance, and material properties on the midpoint deflection and deformation profile are considered. This paper also presents analytical method for determining deflection of fully clamped thin circular plates. The plates are made from a rigid perfectly plastic material and subjected to transverse localized and uniform impulsive loading. The essence of the model is to describe deformation profile with the aid of appropriate function based on the type of distribution of load and to performing upper bound analysis. It provides a way of studying and understanding the plastic deformation of impulsively loaded circular plate. The solutions obtained are in very good agreement with different set of experimental results.
