Распространение упругих волн в ортотропной пластинке от динамического воздействия ударника часть 1. Модель распространения волн

Abstract

The present paper is devoted to mathematical modeling of the elastic wave’s propagation process, with generated from a impact interaction of the solid body, in the orthotropic Uflyand-Mindlin plate, whose dynamic behaviour is described by the wave equations taking the rotary inertia, shear deformations and curvilinear anisotropy into account. Also in the present investigation stresses in the contact area and in other typical points is obtain. Behind the wave fronts, the solution is constructed in terms of asymptotic expansions unknown functions in degree series on the Legandr’s polynomial and Lor an series near fixed point.

Работа посвящена математическому моделированию процесса распространения упругих волн, образующихся от ударного воздействия, в ортотропной пластинке типа Уфлянда-Миндлина, обладающей криволинейной анизотропией и определению напря-жений в месте контакта и различных характерных точках мишени. Для определения искомых величин на фронтах волн используются асимптотические разложения неиз-вестных в ряды по полиномам Лежандра и в ряды Лорана вблизи фиксированной точки.
