Van der Meer, F.P. Sluys, L.J. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2015-12-31 Abstract This paper presents a new damage model for simulating fatigue-driven delamination in composite laminates. This model is developed based on the Thick Level Set approach (TLS) and provides a favorable link between damage mechanics and fracture mechanics through the non-local evaluation of the energy release rate. Previously, this approach has been applied in the context of quasi-static continuum damage models. In this work, the thick level set method is translated to an interface model. The new interface damage model can be applied to quasistatic and fatigue simulations. It benefits from the kinematic flexibility of interface elements and preferable use of fracture mechanics for fatigue analysis. A 3D model is developed based on this approach and the obtained numerical results are validated with analytical and experimental data.
