Vers une nouvelle stratégie PGD pour la simulation numérique de structures élancées

Effective models for slender structures derived from well-known theories are justified within the limit of a small thickness, and may therefore prove limited for intermediate slenderness. On the other hand, direct 3D simulation of such structures is…

Control of the accuracy and improvement of the convergence rate of a LATIN-based multiscale strategy for frictional contact problems

This paper deals with the control and improvement of the convergence of the interface contact quantities in the framework of a multiscale strategy for the resolution of time-dependent frictional contact problems. The considered strategy is the…

Model-Driven Digital Volume Correlation: A Step Forward in Experimental Analyses of Metamaterial Deformations

In experimental studies involving large deformations, directing correlation algorithms to accurately capture deformed configurations may be very challenging. This task becomes particularly pronounced in metamaterials with periodic mesostructures,…

Porous hydrogel promoting spontaneous organoid formation for bone reconstruction : implementation in a perfusion bioreactor

The physiological environment of living tissues is inherently three-dimensional (3D), posing a significant challenge for in vitro tissue engineering to recapitulate the complex cell-cell and cell-matrix interactions that govern tissue development…

Multiscale modeling of cracking of a reinforced concrete element for the evaluation of leakage rates in severe accident situations

Given the aging of concrete and the need to extend the lifespan to cover long-term operations of nuclear power plants, it is essential to have the tools needed to predict the evolution of concrete properties and the associated consequences on…

Improving three-dimensional visualisation of cellular porosity in human dentin using two-photon microscopy

Three-dimensional visualisation of dentin cellular porosity is essential to understand the mechanosensing response of human teeth. However, the inherent light scattering nature of dentin and its refractive index mismatch limit the imaging depth of…

Cellular porosity in dentin exhibits complex network characteristics with spatio-temporal fluctuations

According to the current hydrodynamic theory, teeth sensitivity is mediated by odontoblast cell processes which can be activated by fluid flow in the pericellular space of bulk dentin. To better understand the possible spatial extent of such…
