On the available relevant approaches for fatigue crack propagation prediction in Glare

This paper provides an overview of the various relevant approaches presented in the literature to predict the crack propagation behaviour of fibre metal laminates. The approaches, consisting of phenomenological, analytical and finite element methods, are discussed in this paper with respect to their applicability on the fatigue crack growth behaviour of the fibre metal laminate Glare. It can be concluded that the phenomenological methods are not suitable for Glare, because the complexity of the mechanisms cannot be described by the simplicity of the proposed methods. The analytical methods and the finite element models describe the occurring mechanisms and approximate the crack growth behaviour, but are limited in their current form.
