Zeitverlauf der Spannungs- und Dehnungsverteilung in luftstoßbelasteten Stahlplatten

Abstract
The stress and strain distribution in an impulsively blastloaded plate is far from equilibrium. Partof 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 area-load. Stress and strain is time dependend 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 dependent stress and strain in elements that correspond to the nodes will be discussed.
