Abstract

L'invention concerne la modélisation des interactions entre une onde incidente et un obstacle, notamment dans le domaine du contrôle non destructif. Selon l'invention, on maille la surface de l'obstacle et l'on attribue au moins une source (Si) à chaque élément de surface (dSi). On calcule ensuite des conditions aux limites en chaque maille de l'obstacle et l'on en déduit des valeurs de source. A partir d'une matrice d'interaction et de ces valeurs de sources, on estime une grandeur physique représentative de l'interaction entre l'onde et l'obstacle, en tout point de l'espace.
