Course/seminar

This talk focuses on accelerating the design of microfluidic heat sinks via topology optimization of the conjugate heat transfer problem. The computational bottleneck of this iterative process is the numerical solution of the Navier-Stokes (NS) equations due to their nonlinearity. The approach presented in this talk leverages the Proper Orthogonal Decomposition (POD) method to develop a Reduced Order Model (ROM) for the NS equations including a Brinkman term.

The welfare cost of social pressure

Abstract :

The ambitious goal of reaching net-zero emissions in aviation by 2050 can only be met by science-based disruptive innovations, including those that have the potential to reduce aircraft structural weight. Based on the hypothesis that composite materials and structures are currently not used to their full potential, a new approach for the inverse design of composite materials and structures across different spatial scales will be presented.

CEFISES SEMINAR - QUENTIN RUYANT

Séminaire du CEFISES avec Brigitte Van Tiggelen (Science History Institute)

Lattices materials range from open and closed cell foams across a wide range of length scale to micro-architectured, multi-phase solids that are manufactured by additive manufacture. Size effects are important too: lattices with struts of small diameter are subjected to high gradients of strain in bending and are consequently have a higher material strength than large scale lattices. The focus of this talk is on the effect of filling of a 2D hexagonal lattice or a 3D Kelvin lattice upon their macroscopic stress versus strain responses.

Average Incremental Cost (AIC) Pricing for a Surplus-Maximizing Two-Sided Multi-Period Non-Convex ISO Auction Market

Abstract :

The last decades have shown impressive progress regarding the strength and ductility compromise of steels. Yet, the resulting refined and complex microstructures lead to fracture mechanisms which are not captured by traditional forming and failure indicators.
