Generation automatique de maillages hexaédriques pour des applications en géophysique à l'échelle régionale

L’exploration géophysique nécessite des maillages de haute résolution pour modéliser efficacement la Terre. La méthode des éléments spectraux est très utilisée en géophysique pour ses qualités d’efficacité et de parallélisabilité, mais nécessite des…

Efficient modeling of spiral strands subjected to biaxial bending and variable axial force

Spiral strands exhibit nonlinear hysteretic bending behavior due to their helical geometry and interwire frictional contact interaction. In this study, an efficient framework based on computational homogenization is proposed, in which a spiral…

Régularisation à gradient implicite avec une métrique Riemanniene pour les matériaux quasi-fragiles : anisotropie induite de l'endommagement et interactions non-locales évolutives

Plusieurs formulations non-locales où les distances d’interaction évoluent en fonction des champs mécaniques ont été introduites dans la littérature pour pallier certains effets indésirables observés avec les formulations conventionnelles à…

Thermal and Transfer Behaviour Modelling in Concrete Incorporating Seashell Co-products

In order to reduce environmental impact of construction sector, by-products from other industries must replace classical raw materials in concrete. In parallel, seashell production in the word represents approximately 17 million tons [1] and their…

Mechanical behaviour of concrete based on aquaculture co-products

A possible way to reduce CO2 emissions linked to cementitious materials is to use alternative resources, particularly co-products from other industries. Oyster shell co-products are a calcareous resource produced by aquaculture currently available…

Threshold of Saturation Degree of Unsaturated Sand to Cause Liquefaction Considering the Sample Volumetric Strain: Modelization and Experimental Laboratory Investigation

This paper aims to determine a non-liquefiable domain corresponding to the threshold of saturation degree where liquefaction does not occur under cyclic loading. To determine this threshold, sample volumetric strain at liquefaction state of…

Numerical and experimental study of echogenicity in 3D-printed tissue-mimicking materials

The main focus of this work is the echogenicity of a 3D-printed synthetic composite material that mimics the acoustic properties of cardiac biological tissues to provide ultrasound images similar to those obtained during interventional cardiology…
