Abstract

Based on a Dugdale-type approach for cancelling the singularity at the crack tip, an attempt was made to predict the overall stress distributions, as well as the size of the plastic zone found in notched metal matrix composite plate. The work was developed by considering notched, unidirectionally reinforced fibrous metal matrix composite plate under uniform normal tension load. Predictions of the proposed method were compared with the experimental results, and a fairly good agreement was observed. Simple closed form expressions for the local stresses and fracture strength are provided.
