Abstract :
For the solution of mixed problem for a system of hyperbolic equations with variable coefficients which is modeling elastic disturbance propagation in an inhomogeneous strained solid the method of finite differences is used. The influence of inhomogeneous strained state on the velocity of the disturbance propagation is studied.
