Thermal Management of Integrated CMOS-Si Photonics Optical Transceivers KU Leuven
The infrastructure behind the internet are data centres, where data are stored and processed centrally. Transporting large amounts of data inside the data centre requires a significant amount of energy. To improve the energy efficiency of data transport, the classical electrical connections are being replaced with optical fibres. Traditional electrical input-output (I/O) faces multiple bottlenecks: the bandwidth-distance-power trade-off and ...
Development of an optimized multiscale model for the simulation of metalworking processes. KU Leuven
Effect of forming process on fatigue fracture behaviour of high strength steel. KU Leuven
In modern society, the application of High Strength Steels (HSS) has been proven to be highly versatile. Small as well as large scale constructions benefit from the enhanced mechanical properties of these metals. Through a high strength-to-weight ratio, substantial weight reductions can be achieved, whilst maintaining overall performance and safety. Additionally, a higher strength contributes to an increased maximum payload and structural ...
Fracture toughness in carbon fiber composites, investigated by advanced multi-scale imaging (ToughImage) KU Leuven
The excellent sustainability potential of carbon fiber composites is not yet fully exploited due to their relatively low damage tolerance and difficult characterization. A key property, in this regard, is fracture toughness, which controls the damage development and is highly needed for damage simulation. Unfortunately, micro- and macroscale measurements of this property remain challenging. Thus, there are still many unknowns, especially in ...
Creep of synthetic fibre reinforced concrete. KU Leuven
As the most widely used construction material, concrete is constantly in development with continuous advances made in the fields of material science, concrete technology and reinforcement systems. The development of fiber reinforced concrete (FRC) has significantly impacted all three fields. Since the first trials with FRC in the 1960s, the material has undergone significant improvements in both the quality of the materials as well as the ...
Experimental Validation of Residual Stress Simulations in Welded Steel Tubes with Digital Image Correlation KU Leuven
As each production process introduces residual stresses in the material, cold-rolled steel tubes are not delivered stress-free. The motivation of this research can be traced back to the laser cutting of tubes. During the cutting process, residual stresses are relieved, which causes deformation of the tube and a reduction of the precision of cut. Residual stresses also play a role in stress corrosion and sudden collapse of tubular ...
Development of a user-friendly virtual material characterization toolbox KU Leuven
Towards creation of artificial plant tissue through 3D food printing KU Leuven
The global food market is constantly evolving due the growing demand for food and changing consumer preferences. Public interest in the concept of personalized foods with tailor made flavor and dietary properties is increasing steadily. In response to this, digital technologies such as additive manufacturing (AM, also known as 3D printing) are being considered for designing and fabricating food in a more flexible manner. Recently, an ...
From full-field data to spatial uncertainty KU Leuven
“Lighter is better” is quickly becoming a new mantra in mechanical engineering designs, leading to structures that are becoming increasingly designed up to their performance limits. As a result, uncertainty quantification (UQ) is quickly gaining in importance to assess the reliability of these structures, given typical variability and/or uncertainty an analyst is faced with. However, these reliability estimates are only as accurate as the ...
