摘要：
The objective of this paper is to show the advantages of the cohesivecrack model for predicting fracture of V-notched components. Criticalvalues of the generalized stress intensity factor can be obtained fromthe knowledge of the material softening function and the elastic parameters,avoiding a cumbersome experimental work. The results were checked successfullyagainst experimental ones, from other authors, in different materials: steel,aluminium, PMMA and PVC. A non dimensional formulation of the fracturecriterion for sharp V-notched components was obtained and a simpleapproximate expression derived for easy appication.
