Nonlinear vibro-thermal-acoustical damage imaging in composites by selective activation of defects using time-reversal elastic waves Ghent University
Fiber reinforced polymers (or composites) have excellent specific stiffness/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 susceptibility to internal defects which might compromise their structural performance. The goal of this project is to develop a low-cost and time-efficient non-destructive inspection ...
Monitoring of self-healing within cementitious materials including superabsorbent polymers by means of elastic waves. Vrije Universiteit Brussel
enables the improvement of the self-healing ability through a more
continuous water supply. Using surface ultrasonic measurements, the
closure of cracks was monitored over time and could be correlated to
microscopic analysis, but no information regarding healing at different
depths is available. Also, the link with the regain in mechanical
...
High-throughput field phenotyping using a drone with RGB imagery. Exploiting the spectral, spatial and temporal dimensions KU Leuven
Altered climatic conditions leading to more frequent and intense abiotic events (e.g. drought or heatwaves) and biotic stresses (pathogens and pests) are going to impact on our food system endangering the access to safe, nutritious and sufficient food. To mitigate the negative effects, the adaptation of crops to future climate has to go also hand in hand with an increase in global crop production in order to achieve the estimated demand for ...
Ph.D. position: Neighbouring grain effects in metals with strong anisotropy KU Leuven
The fundamental definition of stress is the force per unit area applied to the material. The practical implementation of this definition entails a scale dependence, since the area onto which the load is applied is considered. When a load is exerted on a metallic material the global macroscopic stress can be significantly different from the local microscopic stress, for example in a single grain. For metallic materials with strong anisotropy, ...
Next-generation phased array based Ultrasonic Polar Scan system for the characterization of visco-elastic materials KU Leuven
Non-destructive testing (NDT) refers to techniques that are used in the life-cycle of a structural component to investigate their quality, functionality and 'health' without destroying the object, nor affecting its properties. The development of NDT techniques is ever-evolving and needs continuous upgrading because of the emergence of new industrial materials, the increasing demand to more sensitive and more quantitative characterisation and ...
Developing Tip-Enhanced Raman Spectroscopy for advanced nanoelectronics KU Leuven
Metrology and materials characterization are critical components in the development of advanced nanoelectronics structures for both CMOS and more exotic applications. Within the family of characterization techniques, Raman spectroscopy is of particular interest due to its non-destructive character and exceptionally fast time-to-result. The technique is uniquely sensitive to mechanical stress, chemical composition, doping and crystallographic ...
Next-generation phased array based Ultrasonic Polar Scan system for the characterisation of visco-elastic composites KU Leuven
Quality control of fresh concrete by advanced dispersion and attenuation characteristics of stress waves Vrije Universiteit Brussel
Numerical and experimental optimization of blind rivet nuts for novel applications KU Leuven
The interest in optimized lightweight and durable structures for automotive and aerospace applications has become more prominent than ever. This is driven by the pressing need to save energy and reduce emissions. The latter often results in the concept of multi-material design, sparked by new emerging materials, challenging well established mechanical joining techniques. A Blind Rivet Nut (BRN) joint is an example of such a mechanical joining ...
