Abstract
The symmetrical problem of two transverse cracks in an elastic strip with reinforced surfaces is formulated in terms of a singular integral equation. The special cases of one central crack or two edge cracks are discussed. Numerical methods for solving the problems with internal cracks are outlined and stress intensity factors are presented for various geometries and degrees of surface reinforcement.
Résumé
Le problème symétrique de deux fissures transversales dans un feuillard élastique dont les surfaces sont renforcées, est posé sous forme d'une équation intégrale singulière. On discute les cas spéciaux d'une fissure centrale ou de deux fissures de bord. Des méthodes numériques pour résoudre les problèmes relatifs à des fissures internes sont proposées, et on présente les facteurs d'intensité des contraintes dans le cas de diverses géométries et de degrés de renforcement des surfaces.
