Data-driven material modeling based on the Constitutive Relation Error

Prior to any numerical development, the paper objective is to answer first to a fundamental question: what is the mathematical form of the most general data-driven constitutive model for stable materials, taking maximum account of knowledge from…

Piezoelectric polymer generators: The large bending regime

There is an important difference between piezoelectric polymer films and solid crystals for the application of piezoelectric generators. In the case of polymers, the optimal piezoelectric response imposes a large bending regime. Starting from the…

New Refined Experimental Analysis of Fungal Growth in Degraded Bio-Based Materials

When exposed to different building environmental conditions, bio-composite materials, such as hemp mortars, represent a risk of mold proliferation. This later plays a critical role in the biodeterioration of the materials when their physical…

An Integrated Workflow for Solving Parametric Nonlinear Problems Through Reduced Order Modeling

Reduced-order modeling methods, like Proper Orthogonal Decomposition (POD), Reduced Basis (RB), and Proper Generalized Decomposition (PGD), are well established in Mechanical engineering for their effectiveness in achieving efficient numerical…

Reduced order modeling of blood perfusion in parametric multipatch liver lobules

In this paper, we present a computationally efficient reduced order model for obtaining blood perfusion profiles within parametric functional units of the liver called 'lobules'. We consider Darcy's equation in two-dimensional hexagonal lobule…

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…

Apprentissage non-supervisé de lois de comportement non- linéaires avec réseau de neurones thermodynamiquement consistent par minimisation de l'erreur en relation de comportement modifiée

Cet article propose une méthode d’apprentissage de lois de comportement nonsupervisé, fondée sur la minimisation de l’erreur en relation de comportement modifiée. La loi de comportement, en termes de loi d’état et d’équation d’évolution, est…

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…
