Abstract:
Results of numerical simulations of wave formation in an oblique symmetric impact of metal plates by the method of molecular dynamics are presented. In this case, the impacting plates experience the same loading conditions as in explosive welding. It is demonstrated that the evolution of waves on the interface between the welded plates is caused by self-induced oscillations in the vicinity of the contact point. A mechanism of building-up and sustaining of self-induced oscillations is proposed on the basis of numerical calculations performed.
Keywords:molecular dynamics, oblique impact of plates, waves on the interface, numerical simulation.
