Features of the wave field in a finite body with a noncentral hole

Waves of elastic stresses in the doubly-connected domain

“…In connection with this, the study of dynamic wave processes in deformable multiply connected media in order to determine the nature of possible damage has, in addition to purely scientific interest, an important applied value. In general, the number of works devoted to dynamic problems, taking into account a number of weakening factors, is very small, they do not consider all aspects of their performance under the conditions of nonstationary external loads [1][2][3][4]. However, the interest in these problems, primarily due to the importance of solving complex practical problems, is great, and further improvement of numerical methods in various modifications with the use of increasingly sophisticated computer technology should lead to a substantial development of this direction.…”
