Mechanics

Numerical simulations of concrete specimens with the gradient-enhanced Eikonal non-local damage model

ccurately predicting the response of structures subjected to complex loadings is a challeng-ing task in civil engineering. In particular, studying cracking nucleation and propagation is essential to as-sess structural performances. Quasi-brittle…

Numerical and analytical studies of attenuation coefficient in 2D matrix-inclusion composites with randomly distributed circular inclusions

This paper studies the analytical and numerical evaluation of the scattering-induced attenuation coefficient of elastic waves in 2D matrix-inclusion composites with a random distribution of inclusions. An analytical self-consistent homogenization…

Effects of dynamic cell culture conditions on 3D spatial reogarnization of MSCS/HUVECS spheroids in the context of bone tissue

We aim to observe the development and reorganization of MSCs and HUVECs in Pullulan/Dextran hydrogels supplied with nHAp under dynamic culture conditions in a perfusion bioreactor.

Perfusion of MC3T3E1 Preosteoblast Spheroids within Polysaccharide-Based Hydrogel Scaffolds: An Experimental and Numerical Study at the Bioreactor Scale

The traditional 3D culture systems in vitro lack the biological and mechanical spatiotemporal stimuli characteristic to native tissue development. In our study, we combined porous polysaccharide-based hydrogel scaffolds with a bioreactor-type…

Benefits of non-linear structural analysis for optimising the seismic assessment and retrofitting of a CEA laboratory

Within the scope of extending the service life of a CEA nuclear facility, a seismic assessment using non-linear transient analysis was carried out between 2017 and 2019. The facility in question was built in the early sixties and was not designed to…
