    Description / Table of Contents: Résumé On évalue les propriétés de résistance à la rupture d'un barreau et d'une plaque, en alliage d'aluminium 2024, selon des méthodes standard et non standard. Les matériaux sont essayés après divers traitements thermiques conférant des microstructures différentes en ce qui regarde la taille et la dispersion des précipités de durcissement. On analyse la sensibilité de divers paramètres de ténacité à la rupture vis-à-vis de la microstructure, de la géométrie des éprouvettes et de leur intégration. Des corrélations établies entre paramètres standard et non standard confirment que des procédures d'essai alternatives peuvent être utilisées pour evaluer la ténacité à la rupture de cette famille d'alliage.
    Notes: Abstract The fracture resistence properties of a rod and a plate, both made of 2024 aluminium alloy, are evaluated according to standard and non-standard methods. The materials are tested after heat treatments involving material microstructures different especially as to size and dispersion of the hardening precipitates. The sensitivity of various fracture-toughness parameters to microstructure conditions, specimen geometry, as well as their interactions is analyzed. Correlations established between standard and non-standard parameters confirm that alternative testing procedures are adequate to evaluate the fracture toughness of this alloy.
