    Description / Table of Contents: Résumé Une analyse photoélastique de contraintes a été utilisée pour déterminer les facteurs d'intensité de contraintes dans le cas de 2 types de fissures au voisinage d'un piètement radial placé dans un récipient sous pression cylindrique. Des relations empiriques sont présentées et validées par des essais sur 35 modèles. On montre également que les valeurs relatives à des fissures latérales peuvent être déduites de celles que l'on peut prédire pour une fissure traversante dans une tôle, en appliquant un facteur de correction de courbure.
    Notes: Abstract Photoelastic stress analysis has been used to determine stress intensity factors in two types of cracks in the vicinity of radial nozzles in cylindrical pressure vessels. Empirical relationships are presented and validated by tests on 35 models. It is also shown that the values for lateral cracks can be deduced from those predicted for a part-through crack in a plate by applying a curvature correction factor.

    An experimental investigation into the buckling of cylindrical shells of variable-wall thickness under radial external pressure (1979)
    Springer
    Experimental mechanics 19 (1979), S. 87-92

    Notes: Abstract Cylindrical shells, with wall thickness-to-diameter ratios varying in steps from 1:2000 to 1:500 are used in large floating-roof storage tanks, where buckling under partial vacuum is a potential risk. To examine the validity of several methods of analysis, aluminum models with a nominal diameter of 150 mm were tested. Some models exhibited a sudden buckling, at the pressure predicted by one of the methods of analysis, others deformed at increased rate as the critical pressure was approached. A gradual change in, modal-buckling pattern, under decreasing pressure, was also observed.
