Computational damage identification and propagation in complex composite structures: Efficient and robust damage detection and diagnosis. KU Leuven
Houyu Lu’ work will focus on developing a new comprehensive computational scheme for critical, online decision making for optimal condition-based maintenance of safety critical composites. Nowadays the transport sector operates at a fixed-interval, conservative maintenance strategy which reduces the availability of the structural product (e.g. aircraft) with simultaneous costs for the operator and passengers worldwide. The proposed project ...
Population-based damage detection for civil engineering structures KU Leuven
Damage-sensitive features used in vibration-based structural health monitoring (SHM), such as strains or natural frequencies, are often influenced by operational and environmental conditions, for example temperature. This complicates damage detection. Although several techniques have been proposed in the literature to differentiate between damage and operational and environmental conditions, this remains a challenge. This proposal ...
Vibration-based Damage Detection with Compressive Sensing and System Identification KU Leuven
This research is driven by the high interest of industry to develop novel nondestructive testing (NDT) methods to detect defects in complex composite parts in a limited inspection time. Classical NDT methods often rely on thermal imaging techniques and on ultrasound. Within this PhD project, vibro-acoustic signals will be exploited to detect and identify damage in composites. The goal is the development of a technique, which is very ...
Enhancing Damage detection and characterisation technologies for complex marine Structures under Extreme environmental conditions KU Leuven
VThe EU is a world leader in the generation of marine energy, with a capacity of 27.9MW for tidal energy and 12MW for wave energy installed in Europe since 2010 and an increasing horizon with up to 100MW as capacity for ocean energy for 2025. The structures aimed at generating this energy are subject to extreme operational and environmental conditions in the ocean; hence their monitoring maintenance strategies are very challenging. This ...
Computational damage detection and diagnosis in composite structures based on metamodeling aided Bayesian inference scheme KU Leuven
This proposal develops a comprehensive Bayesian diagnostics scheme for the localization and quantification of damage in composite structures based on metamodeling strategy and ultrasonic guided-waves. A surrogate model is constructed in lieu of expensive explicit FE analysis, with numerous training data calculated from the wave propagation model based on the wave and finite element (WFE) scheme. The Bayesian model selection approach is ...
Gene expression profiling reveals potential biomarkers for early detection of DNA damage. University of Antwerp
Development and Application of Novel Signal processing tools for the damagE detection on rotating machinery. KU Leuven
Material characterization and damage detection in layered media through the Ultrasonic Polar scan. Ghent University
Non-destructive testing (NDT) refers to techniques used in the life cycle of a structural part of their quality, functionality and 'health' testing without destroying the object, nor affecting its properties. The development of NDT techniques is constantly evolving and needs continuous improvement due to the emergence of new industrial materials, the increasing demand for more sensitive and more quantitative characterization and quality ...
Design of hafnium oxide nanocrystals as computed tomography contrast agent for damage detection in high-end composites. Ghent University
The demand for light-weight, sustainable and high-performance materials is increasing exponentially. Fiber reinforced polymers offer higher strength-to-weight and stiffness-to-weight ratios than traditional materials such as steel, which allows for energy savings and carbon emission reductions. However, their heterogeneous and anisotropic nature makes their behavior far more complex than these traditional materials. In order to analyze their ...
