Abstract. A scheme of high-precision parallel computing of the problem of diffraction of elastic waves on a system of cylindrical non-circular cavities is proposed. The problem is reduced to the solution of singular integral equations realized numerically. The dependences of stresses at the boundaries of cavities on dynamic and geometric characteristics are presented. The high-precision values of maximum stresses at the boundaries of cavities due to the impact of P - and SV -waves are presented for the first time.

Keywords: dynamic problems of the theory of elasticity, isotropic media with arbitrary holes, plane strain waves, singular integral equations, parallel computing.
