ABOUT DEFINITION OF THE LAW OF CHANGE
OF YOUNG'S MODULUS AT THE ANALYSIS OF LONGITUDINAL OSCILLATIONS OF THE ROD
In the paper method for solving the direct problem for a differential equation of second order with variable coefficients is presented. This equation arises in the analysis of longitudinal oscillations of rods of variable rigidity on the basis of difference schemes. The way of determination of the law of change of Young's modulus is also suggested.
Keywords: coefficient of the inverse problem, difference equation, oscillation, heterogeneous environment.
