Problems and solutions arising during creation of a mathematical finite element model of home-made explosive devices (HEDs) were described. The distinct feature of this model is that it relies on the Lagrangian and Eulerian approaches in order to describe the expansion of the explosive charge’s detonation products and deformation of HEDs’ metal parts. The author determined influence of the type of mathematical contact between interactive media on the accuracy of values of the colatitude opening angle of fragments (fragmentation field), which are formed as a result of an explosion of the HED. The obtained results could be useful for criminalists and help them to carry out a comprehensive judicial technical expertise of HEDs’ explosion.
