Elliptic boundary layer in shells of revolution under normal shock surface loading

Abstract

Asymptotic equations for the elliptic boundary layer in shells of revolution at shock normal surface loading are derived in the present paper. Considered boundary layer type has place only at surface and edge shock loading and is localized in the small vicinity of the front of the Rayleigh surface waves. There are used asymptotic methods together with A. I. Lourier’s symbolic integration. There are obtained elliptic equations discribing the boundary layer behaviour with respect to the normal coordinate and hyperbolic equations defined the boundary layer on the shell faces. Refs 18.
