After half a century of developing fatigue delamination prediction models, where accuracy seems more important than physical understanding, this research aims to merge both aspects. To that aim, strain energy release (SER) within the fatigue load cycle was studied using acoustic emission. The correlation between the measured strain energy...

Current models for delamination propagation prediction in fiber-reinforced polymer (FRP) composites exhibit limitations to explain the physics underlying the mechanisms of damage formation in fatigue. In order to contribute in this field, this research focuses on the study of damage development within a single loading cycle of FRP double...

The interaction between matrix cracks and interface delamination is a major failure mechanism in composite laminates and has been a subject of active research in recent years. Although coupled failure behaviour of composite laminates between matrix cracks and delamination has been observed in experiments, accurate modelling of this phenomenon...

Fatigue and residual strength tests were done on doubler specimens consisting of an ARALL3 (3/2) laminate with a bonded-on fingertip doubler. The primary objective was to determine the effect of fatigue crack length on the residual strenght and delamination onset stress for this type of specimen. The specimens were precracked to variable crack...

A number of experiments were done to investigate the influence of plasticity on the strain distribution in the vicinity of a notch and the occurrence of local failure for ARALL3 plate specimens. Analysis of the results led to the development of a model for the blunt notch behaviour of fibre metal laminates. A preliminary implementation was...

Laméris, J. (author)
The effect of the environment on the fatigue behaviour and residual strength of ARALL-3 has been studied using three types of specimens, varying in structural complexity. In addition to the reference ambient air condition, specimens were aged and/or fatigue loaded in hot/humid air or in sump tank fluid. Environmental fatigue loading of door...

van der Hoeven, W. (author)
Fatigue crack growth and residual strength tests were done on ARALL2 (2/1) laminates with bonded-on doublers. The main test variables were the shape of the doubler (square and fingertip) and the thickness of the doubler (0.5 and 0.8 mm). All coupons had a starter notch in the outer aluminium face sheet of the ARALL2 laminate at the edge of the...

The stress distribution in the vicinity of a notch is investigated as a first step towards a more fundamental understanding of the blunt notch behaviour of fibre metal laminates. The applicability of several analytical methodologies for determination of the stress distribution in the vicinity of a notch in a finite width plate is assessed in...

van Rijn, J.C.F.N. (author)
The blunt notch behaviour of metal laminates has mostly been described using concepts which were developed to describe the blunt notch behaviour of metals. In the current work the applicability of fracture models which were developed for composites to describe the blunt notch behaviour of metal laminates is assessed. It is shown that three...

Oldersma, A. (author)
Composite materials with more than one type of fiber in one matrix are known as hybrid composites. In this work the fatigue behaviour of composite materials is discussed and the behaviour of hybrid composites is related to simple (single-fiber) composites. The properties and the behaviour of hybrid composites can mostly be explained...

The damage development In notched (± 45, 0„, 90, 0-) carbon-epoxy coupon specimens tested under different loading conditions was determined. Constant amplitude tests at R = -1 and R = 0.1 as well as flight simulation tests were performed to establish those stress values for which no damage growth occurs.

The influence of sheet thickness (2 mm and 10 mm) and the influence of laminating (5x2 ram) on the fatigue crack growth properties of the aluminium alloy AL 7010-T 73651 were investigated. Both constant amplitude loading and flight simulation loading were applied. All 2 mm and 10 mm thick sheets were machined from a 150 mm thick plate, i.e....
