| Résumé : | Our measurements on fatigue cracks grown in PVC under plane-strain conditions shows that the width of the observed arrest lines is in agreement with the theoretical results obtained from the Dugdale-Muskhelishvili model. Further, we have shown that the fatigue of one arrest line before rupture requires a large number of loading cycles this number of cycles is constant for every arrest line of a given specimen. Brittle fracture of the specimen occurs when the "stress-intensity factor" K first introduced by Irwin reaches a given value. © 1971 Wolters-Noordhoff Publishing. |
