“…The experimental series, like refs. [1,2], detected selectivity in the growth of perturbations of a certain wavelength. Among the whole perturbation set present on the sample surface due to its polishing, only the perturbations of wavelength λ=500µm grow.…”

Results of numerical simulations of the interface coating influence on the shear instability growth in oblique collision of metal slabs are presented. The state of materials was described in the elastic-plastic approximation. The dependence of the perturbation amplitude on the coating thickness and behavior were studied. The computations were conducted on a multiprocessor distributed-memory computer.

“…When certain conditions in impact angles γ and contact point velocity υ K are met, an oblique impact of metal layers is attended with wave formation at the interface: Kelvin-Helmholtz instability develops at the interface [1,2]. These issues were discussed in detail at Conference Parallel CFD 2003 [3].…”
