Abstract

Failure of masonry from blast loads is perhaps one of the most complex events to analyse. The failure mechanisms are complex, but must be accurately represented if the predictions are to be realistic. This paper describes the use of novel computer based methodologies to predict the damage and collapse of masonry structures. The technique that has been developed uses a combination of an Eulerian finite difference code called GRIM, and a modified version of the DYNA3D finite element code. GRIM was developed by DERA and is used to predict the complex blast loads from an internal explosion in a structure. The modified version of DYNA3D was produced by FNC and used to predict the response of the structure, using the GRIM data as input. The validation of the
