La détermination de la tenue mécanique de points soudés est un enjeu industriel important, eten particulier dans le cas d’aciers à Très Haute Résistance. Actuellement, l’essai de tractionen croix est l’essai mécanique le plus répandu caractérisant la tenue des points soudés.Toutefois, l’étude de l’influence des différentes zones constituant le point soudé sur la tenueest difficile en se basant sur cet essai.Un essai d’enfoncement de coin a été développé afin de caractériser les ruptures interfacialesdes points soudés. Une section transverse d’un point soudé est observée tandis qu’un coin estinséré entre les deux tôles soudés. Une caméra CCD enregistre l'observation de lapropagation de la fissure.Le pliage limité des tôles durant la fissurat...
