Abstract

In the present work it was treated, exhaustively, a mathematical method, useful in computer simulation of pulse propagation in an elastic medium with periodical inhomogeneities. It was considered the general case and, in the end it was took into the conssideration the particular case of an elastic semifinite rod that has a periodical variation depending on distance of Young modulus. 1 Introduction The propagation of short pulses of ultrasound in solid media is a very complicated problem because this imply to formulate theoretically and to investigate experime
