Abstract

This paper solves the problem of harmonic elastic oscillations of a layer with two through holes on whose surface a normal pulsating pressure acts. The boundary value problem is reduced to a system of integral equations, which is solved numerically. Examples are given, where the peculiarities of the distribution of circumferential voltage in frequency are investigated depending on the distance between the holes and Poisson’s ratio.

 

Keywords: harmonic oscillations, layer with two holes, integral equations
