Abstract

Large inelastic deformations of T-beams subjected to impulsive loads G.N. Nurick," N. Jones& & G.V. von Alten-Reuss" ^Department of Mechanical Engineering, University of Cape Town, South Africa ^Impact Research Centre, Department of Mechanical Engineering, The University of Liverpool, UK ABSTRACT Experimental test results on T-section aluminium alloy beams with fully clamped ends, which are subjected to a uniform impulsive load distributed over the entire span, are presented in this paper. A theoretical method, which was developed previously for beams with rectangular cross-sections, is modi- fied to predict the behaviour of beams having a T-shaped cross-section. A satisfactory correlation is found between the theoretical predictions and the corresponding experimental results, with the experimental data generally bounded by the theoretical predictions which use inscribing and circumscribing curves to the exact yield surfaces.
