Abstract : Explosion dynamics is concerned with the response of structures to intense pressure loadings from shock waves. Most interactions that occur in practice are very complex, so that scaling laws are often employed to reduce the number of independent variables. Very often, this makes the results easier to interpret. Here, new similarity variables are introduced which lead to flatter response curves than those obtained previously. The energy transfer from the fluid to the structure is treated by computation of the fluid work done in the structure and the increase in elastic energy stored in the structure. (Author)
