## NUMERICAL ANALYSIS OF THE PROPAGATION OF A DISTURBANCE IN STEEL USING THE ANSYS PROGRAM

The paper presents harmonic analysis for the propagation of a disturbance in a simple compressible elastic structure made of steel (a cubic cube measuring 5×5×5 cm). The impact of initial compression or stretching on the propagation speed of the disorder was assessed. It has been shown that in relation to the reference model, i.e. the model without preliminary interactions, there is a change in the speed of propagation of the disturbance and change of the velocity amplitude.
