Numerical Simulation of Three-Dimensional Processes of the Interaction of Elastic-Plastic Bodies with the Product of Detonation in Eiler Variables by Abuziarov MH* in Crimson Publishers: Peer Reviewed Material Science Journals

 

Experimental and theoretical investigation of the processes of interaction and acceleration of deformable solid elasto-plastic bodies with the products of detonation is a complex spatial problem. Interaction with the detonation wave can cause stresses in the elastoplastic body, which considerably exceed the yield strength and substantially deform it during the contact. This process of deformation is very short and, in fact, detonation products can accelerate the body whose shape varies significantly and differs from the initial one. With the development of computer technology, it became possible to simulate these processes numerically. When solving such problems, it is necessary to take into account the processes of initiation and propagation of detonation in solid explosives with the generation of shock waves by expanding explosion products and their interaction with elastoplastic bodies, significant deformation and displacement of these bodies.
