Physics

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…

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…

Debonding Analysis of Fibre Reinforced Polymer Anchors in Concrete via In-Situ X-Ray Microtomography Tests Coupled to Volume and Digital Image Correlation

Background Externally Bonded (EB) Fibre Reinforced Polymer (FRP) strengthening systems are effective solutions for enhancing structural members’ flexural behaviour. However, some issues are encountered near joints, where the stress transfer between…

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…

Bond behavior of GFRP bars in concrete with carbon nanotubes

This work investigates the adherence of 12.7 mm glass fiber-reinforced polymer (GFRP) bars in concrete with carbon nanotubes (CNT) through pull-out tests. Eighteen specimens were used to investigate the impact of CNT content (0% and 0.05% by weight…
