Laser ultrasonic testing methods for crack detection and plastic deformation monitoring under dynamic loading stress KU Leuven
The possibility to generate and detect guided acoustic waves in plates, plate-like or tube, cylinder-like structures for the detection of defects such as cracks and delaminations is well recognized in the field of non-destructive testing (NDT). Timely detection of defects in an early stage prevents them to grow to a level on which they cause failure of components, which can go along with great human and economic loss. NDT is becoming more ...
Multi-scale Approach for Fatigue Loading of Cracked Steel Fibre Reinforced Concrete under Tension KU Leuven
The limited tensile resistance of concrete stimulated the development of steel fibre reinforced concrete (SFRC), consisting of a concrete matrix with randomly distributed steel fibres and characterised by an improved post-cracking behaviour. Despite the various non-structural SFRC applications, its use is still restricted with respect to its potentials, which is mainly caused by the lack of international design codes. Moreover, structural ...
Compressed Sensing in scanning laser Doppler vibrometry for efficient non-destructive inspection of composite materials Ghent University
Compressed sensing is a novel sampling technique which beats the Nyquist dogma in digital signal analysis. Laser Doppler vibrometric inspection of materials typically requires a dense spatial grid of measurement points. This project will exploit the concepts of compressed sensing in vibrometric inspection. This allows to largely relax the dense measurement grid, which will lead to a time-efficient inspection methodology.

Non-destructive measurement of postharvest changes in lamb's lettuce KU Leuven
A healthy lifestyle is becoming more and more important for the modern day consumer and fresh, minimally processed, ready-to-eat vegetables play an essential role. Lamb’s lettuce (Valerianella locusta) is a popular greenhouse vegetable mainly thanks to these characteristics. It is used as an ingredient in salad mixtures and as a leafy salad making it an ideal healthy food for the modern day consumer. However, lamb’s lettuce plants ...
Damage imaging in Composites by means of Nonlinear Time-reversed Elastic Waves Ghent University
Fiber reinforced polymers (or composites) have excellent specific stiffness and strength as well as corrosion resistance, which makes them very attractive for high-tech applications in aerospace, renewable energy … Though, composites are also known for their high susceptibility to internal defects (introduced during manufacturing cycle, or during in-service loading) which could compromise their structural integrity. Accurate and ...
b0234141Vibration-based post-fire assessment of concrete structures using Bayesian updating techniques KU Leuven
The importance of sustainability and resilience in the design and assessment of structures has increased significantly over the past years. An adequate and efficient assessment of concrete structures in the wake of adverse events such as fire can help achieve this, by ensuring that refurbishment and demolition are not needlessly pursued, while at the same time not compromising on safety. Current practice is however far from this goal, as the ...
HYPERSPECTRAL LASER SCATTER IMAGING FOR A NON-DESTRUCTIVE QUALITY INSPECTION OF FOOD PRODUCTS. KU Leuven
In the agro-food industry, there is an increasing demand for non-destructive, fast and cost-efficient methods for the objective determination of product quality. Several parameters influence the quality of a product, while the importance of each of these parameters may vary amongst people. Optical measurement techniques are often used because of their non-destructive nature. However, the robust determination of both chemical and physical ...
