The contrast between hydro-mechanical behavior of the rock matrix and fracture network systems results in flow partitioning between fracture and matrix systems which is affected by the In-situ stress regime. Fracture flow, Darcy law and free and porous media flow physics interfaces of ... En savoir plus

The thermal management of silicon detectors and related electronics through micro-structured silicon cooling plates is gaining considerable attention for high precision particle trackers. Micro-fluidic circuits are etched in a silicon wafer, which is then bonded to a second wafer to ... En savoir plus

Nondestructive inspection (NDI) of damages (e.g., imperfect or degraded bonding lines) or the remaining strength of adhesively bonded lap joints is critical for the operational safety of aircrafts and vehicles. It remains a challenge to use the conventional NDI to quantitatively infer ... En savoir plus

During the hot extrusion process, a cylindrical pre-heated billet is inserted into a container and is forced by a hydraulic press to flow through a shaped die in order to obtain, as final product, a profile with a constant cross-section (Fig.1). Aluminum extrudates have become prominent ... En savoir plus

There is considerable interest in the possibility of combining NTE materials with normal (positive) thermal expansion materials, to reduce the potential of failure of a material or component due to thermal stress fracture. Finite element analysis (FEM) is used to explore the overall ... En savoir plus

To assess the safety deep geological repositories for nuclear waste, it is important to have a clear understanding of groundwater flow at the interface between the storage vault and the fractured rock. Traditional approaches for modelling groundwater often consider both the geological ... En savoir plus

The bentonite barrier is an essential part of safe nuclear waste repository in granite bedrock. In this work COMSOL Multiphysics® is applied to modeling Thermo-Hydro-Mechanical-Chemical (THMC) processes taking place in a bentonite buffer. The system is studied in different geometries, ...

Hydrogen Embrittlement (HE) is one of the mechanisms responsible for premature failure of structures. In the context of environmental sustainability, it is compelling to improve or conceive new processes and/or new materials capable of reducing fracture induced by HE. We analyzed the ...

In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training ... En savoir plus
