Prykladni Problemy Mekhaniky i Matematyky| Summary: | An approach for studying the effective parameters of bending waves propagating in a thin Kirchhoff plate with stochastically distributed holes of noncanonical shape is proposed. It is based on Foldy's averaging theory and the null-field method for solving the problem of wave diffraction by a local scatterer. The relations for the average velocities of propagation of bending waves in the plate and their attenuation coefficients are obtained. Cite as: Ya. I. Kunets’, V. V. Matus, V. O. Mishchenko, V. V.
