Mathematical modeling of the ultrasonic non-destructive control for the composite materials

Abstract

This article presents the realization of a specialized software application for ultrasonic non-destructive testing of heterogeneous composite materials. Starting with the propagation of plane ultrasonic waves inside an infinite length layer and by using the Debye’s series developing formalism it will determine the conception of a mathematical model adequate to the proposed purpose. The use of this software for an adapted programming language C++Builder5, it will facilitate the further manipulation of the less skilled computer users, the created interface being easy to handle. The results obtained in such way were compared to those obtained through experiments, having as consequence that the mathematical model corresponds to the physical reality and can be successfully used in the determination of mechanical properties or of the integrity state’s of a heterogeneous composite material.
