چکیده
The prerequisite to equip structures with in situ electrical health monitoring systems a meaningful manner is estimate potential damage locations. In this context, an analytical approach model the spatial and temporal evolution of transverse inter-fibre fractures (IFF) exemplified for [Formula: see text] cross-ply laminates under three-point bending. based on tensile load bottom 90°-layer. effective stress computed directly from specimen displacement, whereas strength considered be periodically distributed due material inhomogeneities along specimen. continuous comparison between sinusoidal function allows modelling progressive form IFF. A modified Hann window used consider their effect Experiments same configuration are performed observed IFF tune parameters optimisation procedure, e.g., peak separation sinusoid length window. experiment shows high level agreement. thus capable reproduce experiments minimal computational effort. This makes it highly suitable as input models that rely investigated structure. its current form, limited specified configuration. However, simple easily adapted. It furthermore shown composite terms can accurately described using approach.

Drilling of carbon fibre reinforced laminates – a study
The distinguishing characteristics of carbon fibre reinforced laminates, like low weight, high strength or stiffness, had resulted in an increase of their use during the last decades. Although parts are normally produced to “near-net” shape, machining operations like drilling are still needed. In result of composites non-homogeneity, this operation can lead to delamination, considered the most ...
متن کامل3D FEA Modelling of Laminated Composites in Bending and Their Failure Mechanisms
This paper developed three-dimensional (3D) Finite Element Analysis (FEA) to investigate the effect of fibre lay-up on the initiation of failure of laminated composites in bending. TsaiHill failure criterion was applied to identify the critical areas of failure in composite laminates. In accordance with the 3D FEA, unidirectional ([0]16), cross-ply ([0/90]4s) and angle-ply ([±45]4s) laminates m...

The purpose of this study was to investigate how different materials affect the magnetic resonance imaging (MRI) detectability of interbody test spacers (ITS). We evaluated the post-implantation MRI scans with T1 TSE sequences for three different ITS made of titanium, carbon fibre-reinforced polymers (CFRP) and titanium-coated CFRP, respectively. The main target variables were total artefact vo...
متن کاملOn the Effect of Residual Stresses on the Transverse Cracking in Cross-ply Carbon-polyetherimide Laminates Proefschrift
Two themes form the basis of this study on fibre reinforced laminated composites: namely 'thermal residual stress' and 'transverse cracking'. Thermal residual stresses are inherent to any composite structure and are internal stress within the structure that form during manufacture. Their formation arises from the difference in coefficient of thermal expansion of the fibre and the matrix. These ...
