Strains in Fe/Cr/Fe trilayers and (Fe/Cr)5/Fe multilayers epitaxied on MgO and MgO/SrTiO3

Fe/Cr/Fe trilayers and multilayers are prepared as model systems designed to furnish simple data comparable with calculation results for diffusion properties in nuclear materials. Their structure (epitaxy, residual strains and dislocations) is…

Multiscale Effects of Collagen Damage in Cortical Bone and Dentin

The denaturation of collagen at the molecular level in bone and dentin can impact their structure and properties, leading to increased brittleness in pathological diseases such as osteogenesis imperfecta, dentinogenesis imperfecta, diabetes, and…

Heterogeneity in tribologically transformed structure (TTS) of Ti–6Al–4V under fretting

Fretting wear is a surface degradation process caused by oscillatory motion and contact slipping. During gross slip, high local stresses and plastic deformation in the surface and subsurface can lead to the creation of a nanosized grained structure…

Lifetime response of a liquefiable soil foundation-embankment system subjected to sequences of mainshocks and aftershocks

During their typical design working life, structures are subjected to multiple sequential earthquakes that are divided into clusters of mainshocks and aftershocks. In consequence, the induced seismic damage accumulates due to these several events in…

Differential geometry-based thermodynamics derivation of isotropic and anisotropic eikonal non-local gradient damage models using a micromorphic media framework

The Eikonal non-local damage (ENL) approach models damage as a space-deforming phenomenon that affects the interaction distance between material points. As damage increases, interactions between points decrease, ultimately resulting in no…

A first illustration of a multimodel strategy for coupled multiphysics problems

This contribution proposes a suitable framework for the multimodel simulation of strongly coupled multiphysics problems based on the non-incremental LATIN-PGD method. This strategy relies on introducing an interface between physics, which can be…

Conception d'un test de fretting in-situ pour la tomographie à rayons X

Les assemblages mécaniques sont souvent soumis à des vibrations qui génèrent un micro-frottement au niveau des contacts : du fretting. Ces légers déplacements peuvent générer des fissures de et/ou une usure qui réduisent la durée de vie de l…
