“…=̃2 , (13) where: = ( ), 0 < < 2 is a set of parametric boundary equations, = ( , ), = ( , ), = 1, 2; = ( ), = ( ), = ℎ, = + ℎ 2 , ℎ = 2 , is a set of points of the partition boundaries, ̃1 ,̃2 are known functions, which are determined by (4). After determination of the unknown functions, dynamic stresses of the plate are calculated by dependencies, which are obtained in accordance with representation (7) by providing singular components in the kernels of equations and consequently using Plemelj-Sokhotski formulas:…”
