Abstract

The effectiveness of a two-parameter model, based on linear elastic fracture mechanics concepts, is experimentally verified, using original results and data available from the literature. It is shown that the proposed model can be reduced to a one-parameter model, due to the constancy of the other parameter for fibre dominated laminates, irrespective of fibre and matrix materials and shape of the notch. A comparison with the well-known criteria proposed by Whitney and Nuismer (WN) shows that the WN models are useful for prediction of residual strength of notched laminates, provided the length of the notch is not too large; for large notches the two-parameter model reported here seems to be more effective.
