The impact of a rigid sphere with an elastic layer of finite thickness. (English) Zbl 0869.73018

A ray series method is used to obtain an approximate solution to the axially-symmetric contact dynamic problem in which a rigid sphere hits a homogeneous isotropic linear elastic layer. The result generalizes that on the hitting of an elastic semi-space by a sphere obtained before by A. G. Gorshkov and D. V. Tarlakovsky [cf. Advances in Science and Technology of VINITI, Ser. Mech. of Deformable Solids 21, 76-131, Moscow, VINITI (1990)].
