Stress intensity factor for an infinite transversely isotropic solid containing a penny-shaped crack
M. DahanLaboratoire de Mécanique des Solides, Ecole Polytechnique , 91128 Palaiseau, France
Abstract
A closed form solution of an axisymmetric problem is obtained when an interior surface concentrated loading is applied at a finite distance from the crack. For a general loading applied to the crack surface, the results are independent of the elastic constants and hence, they have the same values as in an isotropic case.
Résumé
On donne la solution explicite du problème axi-symétrique quand des forces intérieures concentrées sur une surface, sont appliquées à une distance finie de la fissure. Pour des charges appliquées sur les lèvres de la fissure, les résultats donnés sont indépendants des coefficients élastiques et ont les mêmes valeurs que pour un milieu isotrope.
