About definition of the law of change of young's modulus at the analysis of longitudinal oscillations of the rod

Abstract

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
