| Safety is paramount in the handling and storage of explosives. There is a long and sad history of serious accidents that have resulted from both mechanical and thermal abnormal and unexpected loadings of diverse severities. The high cost and danger of experimentation has necessitated modelling of scenarios of potential danger. The great flexibility and power of hydrocode packages implementing finite element and difference methods has made their use the natural choice to address this need. However, the use of these codes has often revealed that localised effects arise that are hard to resolve with standard computation meshes; often shear bands or local regions of extreme heating are observed. The question thus arose: could mathematical analysis and/or new sophisticated adaptive methods offer further advances in understanding? Following an initial European Study Group with Industry in 2011, AWE has sponsored a series of mathematics PhD projects engaging UK academics in problems addressing key mechanisms of shearing of, and severe heating of, explosives. This Workshop is designed to showcase the recent progress in this area in the UK and internationally. It will offer ample time for discussion and forging collaborations. |
