    Notes: Three sector elements, two for plane stress problems (PSL and PSN) and one for plate bending problems (BSN), have been developed. Of the three elements, two are based on the natural mode technique. The elements have been applied to typical problems to test their performance.

    Notes: An important limitation of finite element analysis, namely, the need for a large number of small elements in regions of finite or infinite stress concentrations and the difficulties of convergence in such cases, is well known. Rao1 suggested a possibility of overcoming this by developing hybrid techniques combining continuum and finite element concepts. In such techniques, each region of stress concentration is covered by one large ‘primary element’ whose description includes term(s) identifying the type and order of concentration, while the remaining structure is split into a few ‘secondary elements’ which are conventional finite elements. In this paper a procedure incorporating this concept is developed and its effectiveness is clearly demonstrated by successful application to two important examples, one of them with stress singularities. The concept, in fact, can be applied equally well to other two- and three-dimensional problems of continua with discontinuities and concentrations.

    Description / Table of Contents: Résumé On a solutionné les modifications des contraintes an voisinage de l'extremite d'une fissure axiale dans un récipient cylindríque sournis à pression. L'analyse, qui recourt à une approche par équations différentielles, comporte l'étude de la variation d'un paramètre de la courbure, mettant en relation la longueur de la fissure, le diamètre du récipient et son épaisseur. Les résultats sent applicables an cas de fissures de faible longueur, et sent en complet accord avec ceux qu'a obtenus précédemment Folias en traitant le problème par équations intégrales.
    Abstract: Zusammenfassung Für die Spannungen in der Umgebung der Spitze eines axialen Risses in einer dem Druck ausgesetzten zylindrischen Hülle werden Perturbationslösungen ermittelt. Die Analyse, in welcher eine Annäherung über Differentialgleichungen angewandt wird, begreift eine Untersuchung der Änderung eines Krümmungsparameters welcher Rißlänge, Zylinderdurchmesser und Blechdicke miteinander verbindet. Die Ergebnisse sind auf den Fall kurzer Risse anwendbar und befinden sick in voller Übereinstimmung mit denjenigen von Folias, welcher das Problem mit Intergralgleichungen behandelt hat.
    Notes: Abstract Perturbation solutions are obtained for stresses around the tip of an axial crack in a pressurized circular cylindrical shell. The analysis, using a differential equation approach, involves perturbation in a curvature parameter relating crack length to shell diameter and thickness. The results are valid for cracks of small length and agree completely with those obtained earlier by Folias by the method of integral equations.
