    Notes: Conformal mapping regularizes (in the new plane) the singular stress field around the crack tip. So, conventional finite elements can be used in the transformed plane. The inverse mapping of the above elements gives another class of ‘mapped elements’. The crack-tip mapped element is a singular element. Thus, using various elements (the ‘parent elements’) in the mapped plane we obtain an infinity of singular elements, the ‘product elements’. These singular elements are introduced naturally and have no defect, as many other singular elements have.

    Description / Table of Contents: Résum'e L'auteur a proposé un concept pour construire des intégrals indépendantes du parcours dans les milieux isotropes. Il généralise à présent son concept pour construire ces intégrales dans le cas des corps plans anisotropes affaiblis par la présence d'un grand nombre de fissures colinéaires. Ces intégrales sont classées suivant trois catégories correspondant à des restrictions bien définies. En utilisant cette classification, près de cinquante formes générales d'intégrales indépendantes du parcours sont fournies, et, à partir d'elles, une infinité d'intégrales peuvent être construites. Dans de nombreux cas, la forme des intégrales proposées est plus simple que celles déjà connues. Ceci va faciliter leur utilisation, en association avec la méthode des éléments finis ou des methodes experimentales. On donne également plusieurs exemples d'application.
    Notes: Abstract The concept proposed by the author for the construction of path-independent integrals (PI Is) in isotropic media is generalized for the construction of PIIs in anisotropic plane bodies weakened by a number of collinear cracks. The PIIs are classified into three classes satisfying well-defined restrictions. Using this classification about fifty general forms of PIIs are given, from which an infinity of new PI Is can be constructed. In many cases the form of the proposed integrals is simpler than the already known ones. This will facilitate their use in conjunction with finite element or experimental methods. A number of illustrative examples is also given.
