Investigation of the protective properties of cermets of combined structure under high-velocity impact

Abstract

The use of self-propagating high-temperature synthesis (SHS) for the production of cermets of combined structure is considered and a mathematical simulation of the behavior of these materials under high-velocity impact by a projectile is presented.

Mathematical simulation of the behavior of materials and structural elements under multiple impact loading

“…To investigate the behavior of materials under shock-wave loads, a mathematical model is suggested that allows the stress-deformed state and fracture of plastic and fragile materials to be calculated under shock-wave loads in the context of mechanics of continuous media [6,7,[9][10][11]. The dynamic fracture is considered as a process of growth and merging of microdefects due to stresses formed under loading.…”

Computer simulation of the relation between mechanical behavior and structural evolution of oxide ceramics under dynamic loading

“…Of particular interest are investigations into the deformation and fracture processes developing in ultrafine-grained and nanostructured materials under pulsed and shock loading [1][2][3][4]. These investigations provide information on the fundamental strength properties of the materials.…”
