Liu, Y. (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)In this paper, the thick-level-set method is used to model stable and unstable (stick/slip) crack propagation in the dynamic double cantilever beam (DCB) test for unidirectional composite laminates. The thick-level-set method uses a predefined damage profile to describe the fracture process zone and allows<br/>for accurate evaluation of the...conference paper 2017

Latifi, M. (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)This paper presents a new discontinuous damage model for simulating fatigue-driven delamination in composites. Fatigue models commonly describe crack growth using the Paris law which provides the link between the energy released due to delamination and the crack growth rate. A core issue in implementing the Paris law is to accurately compute the...conference paper 2016

Rocha, I.B.C.M. (author), Raijmaekers, S (author), Nijssen, RPL (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)In this work, a combined experimental/numerical approach is used to investigate the effect of water ingression in glass/epoxy composite specimens. Interlaminar shear (ILS) specimens were immersed at 50◦C for multiple durations and tested. Re-dried specimens were also tested. Significant strength degradation of up to 50% was found for wet...conference paper 2016

Rocha, I.B.C.M. (author), Raijmaekers, S (author), Nijssen, RPL (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)In this work a glass/epoxy composite commonly used in wind turbine blades is exposed to a humid environment at an elevated temperature. To research the anisotropic di_usion behaviour observed in unidirectional composite specimens, experimental results of slices cut along the three directional planes of the laminate immersed in demineralised...conference paper 2016

Lahuerta, F. (author), Westphal, T. (author), Nijssen, RPL (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)The aim of this work is to study the thickness effect in static and fatigue tests of glass-fibre unidirectional compression coupons. For this purpose, the self-heating effect, the effect of specimen geometry, and the influence of the manufacturing processes have been minimized. A scaled thickness compression coupon has been designed with the...conference paper 2014
