Abstract

Simulation and experimental validation of the dynamic response of viscoplastic plates M. Stoffel, R. Schmidt, D. Weichert Institutfur Allgemeine Mechanik, Aachen, Germany Abstract In the present paper measured and simulated vibrations of viscoplastic plates under impulsive loading are compared. The aim is to determine how accurately the measured deformations can be calculated by the chosen constitutive and structural theories. A first-order shear deformation shell theory assuming small strains and moderate rotations and viscoplastic laws are applied. The experimental study is carried out with two shock tubes. 1 Introduction In literature several approaches are reported on how to investigate the inelastic dynamic behaviour of structures subjected to impulsive loading experimentally and to simulate the response numerically based on various constitutive models and structural theories. An overview of relevant articles in this field is given e.g. by Jones [7], Stronge and Y
