Roughness Evolution Induced by Third-Body Wear
Jean-François Molinari, Antonio Joaquin Garcia Suarez, Tobias Brink
Surface roughness is a key factor when it comes to friction and wear, as well as to other physical properties. These phenomena are controlled by mechanisms acting at small scales, in which the topography of apparently flat surfaces is revealed. Roughness i ...
New York2024DeepBND: A machine learning approach to enhance multiscale solid mechanics
Annalisa Buffa, Simone Deparis, Pablo Antolin Sanchez, Felipe Figueredo Rocha
Effective properties of materials with random heterogeneous structures are typically determined by homogenising the mechanical quantity of interest in a window of observation. The entire problem setting encompasses the solution of a local PDE and some aver ...
2023Data-driven finite-thickness cohesive elements for frictional interfaces
Jean-François Molinari, Antonio Joaquin Garcia Suarez, Sacha Zenon Wattel, Yannick André Neypatraiky
Model-free data-driven computational mechanics (DDCM) [Kirchdoerfer & Ortiz, 2016] is a new paradigm for simulations in solid mechanics. As in the classical method, the boundary value problem is formulated with physics-based PDEs such as the balance of mom ...
2023Reduced order models for coupled systems
Efficient numerical simulations of coupled multi-component systems can be particularly challenging. This is mostly due to the complexity of their solutions, as mutual interactions may cause emergent behaviors, including synchronization and instabilities. V ...
EPFL2023Advances in Spillway Hydraulics: From Theory to Practice
Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos
Over the past decades, significant advances have been achieved in hydraulic structures for dams, namely in water release structures such as spillway weirs, chutes, and energy dissipators. This editorial presents a brief overview of the eleven papers in thi ...
2023Microscale hydrodynamic confinements: shaping liquids across length scales as a toolbox in life sciences
Philippe Renaud, David Philipp Taylor, Prerit Mathur
Hydrodynamic phenomena can be leveraged to confine a range of biological and chemical species without needing physical walls. In this review, we list methods for the generation and manipulation of microfluidic hydrodynamic confinements in free-flowing liqu ...
ROYAL SOC CHEMISTRY2022Aging investigation of the latest standard dual power modules using improved interconnect technologies by power cycling test
The latest standard "New Dual" power module has been developed for both silicon and silicon-carbide devices to meet the increasing demands in high reliability and high temperature power electronic applications. Due to the new package is just starting to re ...
PERGAMON-ELSEVIER SCIENCE LTD2022Waves at a fluid-solid interface: Explicit versus implicit formulation of boundary conditions using a discontinuous Galerkin method
Jan Sickmann Hesthaven, Khemraj Shukla
An accurate solution of the wave equation at a fluid-solid interface requires a correct implementation of the boundary condition. Boundary conditions at acousto-elastic interface require continuity of the normal component of particle velocity and traction, ...
2019A saddle point approach to an optimal boundary control problem for steady Navier-Stokes equations
Alfio Quarteroni, Andrea Manzoni
In this paper we propose a saddle point approach to solve boundary control problems for the steady Navier-Stokes equations with mixed Dirichlet-Neumann boundary conditions, both in two and three dimensions. We provide a comprehensive theoretical framework ...

Paolo Ricci, Paola Paruta, Maurizio Giacomin, Carrie Fiona Beadle, André Calado Coroado
Abstract The study of scrape-off layer (SOL) is a fundamental step in magnetic confinement fusion research. For example, SOL sets the boundary conditions for the tokamak core and it provides the energy flux toward the tokamak wall. With the goal of improvi ...
