In this paper, we consider the problem of forced oscillations of a rectangular
plate made of dissipative non-homogeneous composite materials. Based on the refined model
of Academician Yu.N. Rabotnov, integral and integro-differential dependencies between
stresses and strains with weakly singular hereditary cores and using the equations of motion of
the plate, an integro-differential equation (IDE) was obtained, which is a mathematical model of
this problem. Using the method of eliminating weakly singular features of integral and integrodifferential
equations (IDE), proposed by Professor F.B. Badalov, a methodology and algorithm
for numerically solving of a system of weakly singular IDE describing discrete models of a
problem have been developed. Using the method of fundamental systems of solutions for
solving the problem of an articulated rectangular plate, an exact solution of the IDE is obtained
that satisfies the corresponding initial conditions.
