Abstract

Deflection and tearing of clamped stiffened circular plates subjected to uniform impulsive blast loads G.N. Nurick, D.M. Lumpp Department of Mechanical Engineering, University of Cape Town, Private Bag Rondebosch, 7700 South Africa ABSTRACT The large deformation of structural components such as beams, plates and shells subjected to blast loads can be predicted with favourable correlation with experimental data. This work deals with the more complex situation of combining these structural components. Experiments using a 100mm diameter circular plate stiffened with a single beam of width 8mm clamped across the diameter of the plate is presented. Beams of thickness 3,4,5 and 6mm were used. Results show that an optimum beam-thickness/plate-thickness combination is required. 1. INTRODUCTION The prediction, as a result of a blast load, of the large deformation of structural components with symmetrical cross-sections such as beams, plates and shells, has b
