Impact Damage Effects and Computational Methods,

Abstract

A special aspect in design technique of military aircraft is the investigation of the structural response to weapon loadings. One of the most critical loading in this field is the fragment impact on tank structures with respect to the hydraulic ram effect. For the analysis of structural response to combined impact and pressure wave loadings a numerical method is presented, modelling the fully three dimensional fluid structure interaction. Examples of application of Eulerian, Lagrangian and coupled Eulerian/Lagrangian formulations are shown, demonstrating the facilities of numerical simulation.
