Numerical investigation of the process of detonation waves interaction with an elastoplastic target. (English)

Authors: Rîbachin Boris, Secrieru Grigore, Guţuleac Elena


The results of the numerical simulation of the detonation wave interaction with an target are presented in this work. The damaged thermoelastoplastic body model was chosen to describe the target material. The solid explosive material (EM) was modelled as an elastoplasic medium before detonation and as detonation gaseous products after its beginning. The detonation process is presented both as stationary and non-stationary models. The EM charge parameters influence the process of plate acceleration.
