Time Dependend Stress and Strain Distribution in a Blastloaded Steelplate

Abstract

The stress and strain distribution in an impulsively blastloaded plate is far from equilibrium. Part of the plate will be elastically strained whilst other part will be strongly plastically deformed. A high explosive (HE) charge, detonating near to a flat steelplate produces an impulsive aerea-load. Stress and strain is time dependent and is different from element to element in the plate. The time-dependend displacement of nodes in the net of finite element calculation and the time dependend stress and strain in elements that correspond to the nodes will be discussed.
