The problem of reducing the stress concentration on the boundary of the cavities medium under the dynamic load action

Abstract

The effectiveness of the use of additional barriers in the form of tunnel cavities of the elliptic section located on the wave propagation to reduce the dynamic concentration of stresses is investigated in this paper. The distribution of dynamic hoop stresses on the boundary of cavities and radial stresses in a medium are studied on the basis of the method combining the use of Fourier transformation in time and the method of boundary integral equations. Fixed time snapshots of stress fields are developed.
