(author)This paper investigates the viscoelastic/viscoplastic/fracture behavior of an epoxy resin. A state-of-the-art pressure-dependent elastoplastic constitutive model (Melro et al. 2013) is expanded to include viscoelasticity, viscoplasticity and a modified damage formulation with linear softening and shrinking pressure-dependent fracture surface. A...journal article 2019

Narayana Swamya, J.K. (author), Lahuerta, F (author), Anisimov, A. (author), Nijssen, R.P.L. (author), Groves, R.M. (author)In this paper, a method has been developed to use thermography for the quantitative analysis of a delamination area under dynamic loading. To demonstrate this method, a coupon was developed with double shear configuration and an initial delamination consisting of a PTFE insert. The coupon was tested under fatigue loading and an infrared (IR)...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
