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…

Principaux facteurs influençant le comportement en compression des cordes textiles : une approche par éléments finis à méso-échelle

Les composites d’élastomèrs/câblés textiles constituent le cœur de la structure des pneumatiques. Sous l’effet des déformations de compression, le renfort textile est endommagé par la formation de défauts de type kink band. Des simulations par…

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…

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…

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…

Pipeline for Semantic Segmentation of Large Railway Point Clouds

This paper presents a novel deep-learning pipeline to segment large railway datasets with minimal manual annotation, notoriously time consuming. The pipeline adapts DINOv2 [11] for labeling point clouds, with tailored self-distillation pre-training…

Acoustics

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…

General Relativity and Quantum Cosmology

Relativistic second gradient theory of continuous media

Variational Relativity is a framework developed by Souriau in the sixties to better formulate General Relativity and its classical limit : Classical Continuum Mechanics. It has been used, for instance, to formulate Hyperelasticity in General…
