Distribution Natural Waves on the Viscoelastic Cylindrical Body in Plane Strain State

In this paper the distribution of natural waves in the viscoelastic disc is discussed. The spectral problem is reduced to solving a system of ordinary differential equations of the first order with variable complex coefficients. The solution of differential equations is expressed by a special cylindrical Bessel functions and Hankel. The frequency equations are solved by numerical methods Muller and Gauss. The problem is solved numerically by the Godunov orthogonal sweep method and Mueller. Compares the numerical results.
