The onset of damage caused by the free-edge effect in plain-woven carbon fiber reinforced plastic (CFRP) specimens with an out-of-plane waviness under tension-tension fatigue loading is investigated. Numerical calculations show that interlaminar and intralaminar stresses close to are higher than equivalent at surrounding edge regions. Using submodels, influence chosen can be better assessed. co...

In this contribution, the causes leading to undesired unevenness on exterior surface of a paper-based sandwich structure during manufacturing process are investigated. This provides insight into parameters that need be adjusted reduce waviness. A finite element model pressing is developed in commercial software ABAQUS and then used analyze formation unevenness. The adopted consists decorative l...

Nanotube-reinforced polymers offer significant potential improvements over the pure polymer with regard to mechanical, electrical and thermal properties. This article investigates the degree to which the characteristic waviness of nanotubes embedded in polymers can impact the effective stiffness of these materials. A 3D finite element model of a single infinitely long sinusoidal fiber within an...

We propose a novel approach to surface flatness characterization in construction that relies on the combination of Terrestrial Laser Scanning (TLS) and the Continuous Wavelet Transform (CWT). The former has the advantage over existing measurement technologies of providing both accurate and extremely dense measurement over surfaces. The latter provides the means to conduct frequency analysis wit...

Collagen plays an important role in the response of the arterial wall to mechanical loading and presumably has a load-bearing function preventing overdistension. Collagen configuration is important for understanding this role, in particular in mathematical models of arterial wall mechanics. In this study a new method is presented to image and quantify this configuration. Collagen in the arteria...
