Factors affecting the numerical modelling of demolition by explosives E. Yarimer" & J.A.M. Lapa& "Department of Civil and Environmental Engineering, University College London, ^Department of Civil Engineering, University of Coimbra, 3049 Coimbra Codex, Portugal ABSTRACT Demolition by explosives produces a dynamical collapse phenomenon the study of which can be pursued either by simplified analytical models or by detailed numerical modelling on the computer. While the former brings valuable general insights, it is the latter which is likely to produce realistic predictions specific to actual cases. After introducing the distinguishing aspects of the problem, the paper discusses the results from two recent numerical analyses: the first using a standard DynaSD material type, and the second, a purpose-made program in which elements of the structure were given elastic properties followed by plastic collapse and a locking phase. The technique used for repres
