Abstract

La résistance à la déchirure ductile des aciers est souvent caractérisée par des courbes exprimant la variation d’un paramètre global (ouverture en pointe de fissure δ, force d’extension de fissure J) en fonction de l’accroissement de fissure Δa. Cet article rappelle les problèmes de transférabilité posés par ces mesures et identifie les facteurs qui la compliquent pour les joints soudés. Il donne des recommandations pour la détermination expérimentale de la résistance à la déchirure des joints soudés.
