Development of novel vibro-acoustic metamaterials with structural load-carrying capacity through a model-based design methodology KU Leuven
The demand for enhanced static or dynamic performance, coupled with rising customer expectations and more stringent regulations, necessitates mechanical systems to comply with increasingly tightening and sometimes conflicting standards. The drive for robustness and reliability requires the systems to have an increased structural stiffness. This, however, contradicts with the trend towards lightweight designs, motivated by environmental ...
Manufacturing of metamaterials by thermoforming and injection moulding KU Leuven
In view of mass manufacturing solutions which merge high narrowband noise and vibration attenuation while preserving good broadband performance, this PhD track will work on design and manufacturing strategies for novel (vibro-)acoustic metamaterial solutions, while considering the integration of porous foam phases. On the one hand, currently used techniques to produce metamaterials, including additive manufacturing, or laser cutting of ...
Enabling the integration of multi-functional reliable metamaterials in real-life industrial applications for enhancing structural and vibrational behavior KU Leuven
The manufacturing industry is fundamental to the technological sovereignty and competitiveness of the European economy. To maintain the leading position, the sector requires continuous innovations, exploring the limits of material properties. This is particularly the case in high-end technology applications, such as lithography machines and micro-electromechanical systems (MEMS) industry, where the limits of conventional materials come into ...
Modelling, analysis and validation of variability effects in vibro-acoustic metamaterials for broadband noise and vibration attenuation KU Leuven
Vibroacoustic metamaterials for broadband sound insulation in building acoustics KU Leuven
Noise coming from traffic, industrial and construction activities or neighbors has a severe impact on people and results in activity disturbance, social tensions and health problems. It is therefore of paramount importance to ensure sufficient levels of sound insulation. This is very challenging, especially for emerging sustainable types of construction such as cross laminated timber (CLT). Recently, a very promising sound insulation concept ...
The influence of size and boundary conditions on the sound and vibration isolation performance of vibro-acoustic metamaterials KU Leuven
This PhD track focuses on the investigation of the dynamics of finite VAMM plates, focussing on (i) the influence of edge effects of finite samples and (ii) transmission reduction by aperiodic design. Model reduction will be used for efficient and accurate finite VAMM performance predictions and energy flow quantification and visualization. Fast (e.g. Bayesian) optimization schemes will be used to optimize VAMM performance under different ...
SOUND INSULATION OF BUILDING ENVELOPE COMPONENTS BASED ON ACOUSTIC METAMATERIALS KU Leuven
Adaptation of building envelope components in the revitalization process of office buildings to dwelling opens several acoustic and thermal challenges, both for the indoor and outdoor environment. Sound insulation properties of building envelope components are crucial for a proper acoustic comfort indoors. The noise present in urban areas is known to dramatically increase when so-called street canyons are formed by arrays of tall buildings, ...
Synergy between top-down and bottom-up fabrication in plasmonics by embedding nanoclusters in metamaterials KU Leuven
In the field of optics both nanoclusters, sustaining localized surface plasmon resonances, and metamaterials, facilitating localized electric and/or magnetic resonances, have received a lot of attention. Their study deals with fundamental scientific questions about strong light−material interactions such as enhanced scattering and highly localized electric fields and is of high relevance for applied research that makes use of a wide range of ...
