Description

A method is described which allows, by means of an experimentally discovered law, the determination of the geometrical characteristics of the detected defects. This determination is based on the properties of focused probes, and particularly on what is called their 'effective ultrasonic beam'. The main result is the ability to describe a defect with a given and known accuracy. Examples are given which show practical applications of the method

Abstract (French)

On decrit une methode qui permet, au moyen d'une loi experimentale, de determiner les caracteristiques geometriques des defauts deceles. Cette determination est basee sur les proprietes des traducteurs focalises et particulierement de ce que l'on peut appeler le 'faisceau ultrasonore utile'. Le resultat principal est leur aptitude a decrire un defaut avec une precision donnee et connue. On donne des exemples d'application pratique de la methode
