Abstract
A non local ply scale criterion was previously developed for predicting the failure of balanced woven ply structures with stress concentrations. This non local criterion was based on the mean values determined over a Fracture Characteristic Volume (FCV). A behavioural model was developed from a classical Continuum Damage Mechanics (CDM) model. The FCV approach and the CDM behavioural model were implemented in ABAQUS and applied to the case of unbalanced woven ply. Comparisons are made between the experimental data and the modelling predictions obtained on plates with open holes, notches and saw cuts. The numerical implementation of this approach is studied in this paper.
