Abstract: | Several difficulties in the double cantilever beam (DCB) tests of multidirectional laminates often prevent valid measurements of the mode I critical strain energy release rate GIc : In this paper, several DCB specimens were analysed with 3D finite element models. The results showed that the undesired effects of residual stresses and of mode-mixity can be minimised. An interlaminar stress based fracture criterion predicts that the GIc of multidirectional specimens is typically 10 – 40% higher than the GIc of unidirectional [08]n laminates. This agrees with the few valid experimental data available. |
