Non-destructive visualisation of marine corrosion forms with X-ray imaging (COROXI). University of Antwerp

Jan De Beenhouwer
Antwerp Maritime Academy, Vision lab
X-ray Computed Tomography (XCT) can visualise internal and external characteristics of an object in 3D in a non-destructive manner. To assess the potential of this technology for the inspection of the occurrence of corrosion on maritime structures, covered with non-metallic layers, such as coatings, macrofouling and calcium deposits, a series of lab experiments will be set up to create a set of reference XCT images linked to well-described ...

Hyperspectral cameras for the efficient assessment of coatings, corrosion and material surfaces (HypIRspec). University of Antwerp

Steve Vanlanduit
Vision lab, Katholieke Universiteit Leuven, Sirris, Industrial Vision Lab (InViLab)
The overall objective of the project is to demonstrate the technical feasibility and economic added value of using of hyperspectral cameras for corrosion inspection and quality control of corrosion solutions (corrosion cleaning, wet and dry coatings and chemical surface treatments). The project focuses on the entire corrosion value chain. On the one hand, these are owners of infrastructure (petrochemical, port, energy), a group of some 100 ...

A coupled local-global structural health monitoring approach for assessing the structural performance of deteriorated concrete components with reinforcement corrosion. KU Leuven

Els Verstrynge
Structural Mechanics, Materials and Constructions

Worldwide, many civil engineering structures reach the end of their designed lifetime. Reassessing their design lifetime or performance for altered load conditions, raises questions on their remaining capacity. This doctoral research aims at developing a local-global structural health monitoring approach for assessing the performance of reinforced concrete components subjected to degradation, in particular corrosion of the reinforcing steel. ...

Damage imaging in Composites by means of Nonlinear Time-reversed Elastic Waves Ghent University

Mathias Kersemans
Department of Materials, Textiles and Chemical Engineering

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 ...

PhairywinD project University of Antwerp

Steve Vanlanduit
Katholieke Universiteit Leuven, University of Mons, Catholic University of Louvain, University of Freiburg, Université Libre de Bruxelles, von Karman Institute for Fluid Dynamics, Sirris, Ghent University, Vrije Universiteit Brussel, Industrial Vision Lab (InViLab)
In this PhD research we will develop a non-destructive testing technique for the automated and quantitative inspection of bare and coated steel structures during manufacturing and operation, using a hyperspectral camera. Whereas the human eye and color cameras perceive three colors in the visible range, a hyperspectral camera is able to capture several tens of images over a wider wavelength range. This facilitates observation of phenomena that ...

Condition assessment and damage modelling of corroding reinforced concrete structures through Bayesian coupled learning models KU Leuven

Els Verstrynge
Materials and Constructions

Condition assessment and lifetime prediction of corroding reinforced concrete structures is a major engineering challenge. In practice, inspection and condition assessment are often based on (qualitative) visual inspections, occasionally complemented by quantitative measurements. Data from local measurements provides information on concrete properties, lay-out of reinforcement or specific damage phenomena such as reinforcement corrosion. The ...

Valorization of nondestructive testing and related materials characterization KU Leuven

Martine Wevers
Physics, Kulak Kortrijk Campus, Structural Composites and Alloys, Integrity and Nondestructive Testing (SCALINT), Soft Matter and Biophysics

The IOF mandate supports valorisation activities in non-destructive testing and structural health monitoring, technologies applied range from ultrasonics to optics. A focal point here is the exploitation of so-called percolation sensors. Technologies already implemented mainly target the detection of wetness in engineering structure in aeronautics and chemical industry to prevent "corrosion under isolation (CUI)". Further successful ...

Nonlinear vibro-thermal-acoustical damage imaging in composites by selective activation of defects using time-reversal elastic waves Ghent University

Mathias Kersemans
Department of Materials, Textiles and Chemical Engineering, KU Leuven

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 ...

BAP-2022-83 Structural Health Monitoring and Predictive Maintenance of Complex Structural Systems KU Leuven

Dimitrios Chronopoulos
Mecha(tro)nic System Dynamics (LMSD)

The deterioration of large infrastructure systems represents trillions of dollars in public and private domains world-wide. Currently, infrastructure asset managers face numerous challenges to maintain their assets. This includes the inability to predict residual service life of the offshore & coastal infrastructure assets as damage accumulation over time (e.g., corrosion in marine environment, docking impacts due to vessels) and ...

SEACHEM project-DC2 position KU Leuven

Raf Dewil
Materials and Constructions, Chemical and Biochemical Reactor Engineering and Safety (CREaS)

The present doctoral candidate (DC2) is part of the European Seachem DN project which involves a total of 10 doctoral candidates (DC1-10) working on a same global challenge. The overarching aim of the SeaChem DN project is to provide high-level training in the offshore cultivation and valorization of seaweed to this new generation of 10 high-achieving doctoral candidates (DC) and equipping them with the transferable and scientific skills ...
