Comparative Hygrothermal Performance of a Mortar Wall with Micronized Miscanthus Fibers versus a Reference Wall: Experimental and Numerical Analysis

Miscanthus fibres are regarded as a sustainable, eco-friendly material with high hygroscopicity and low thermal conductivity. Although promising at the material scale, further wall-scale evaluations are needed. This study investigates the…

Three-dimensional beam-to-beam frictional contact with small-sliding and finite rotations

Abstract Stranded cables, composed of multiple twisted wires, exhibit high tensile strength and flexibility, making them essential in numerous industrial applications, such as mooring lines for offshore structures, overhead conductors, and cable…

Physical-chemical characterization of a crystallinity gradient in a carbon black-filled PEEK laminate manufactured by laser-assisted tape placement

Laser-assisted tape placement (LATP) of thermoplastic composites (TPC) enables the rapid production of laminates. However, during layup, higher cooling rates are expected on the bonded interphases between two plies (in the vicinity of the interply),…

Theoretical and numerical modeling of ultrasonic scattering in polycrystalline materials

The strong interaction between the polycrystalline microstructure and elastic waves makes it challenging to fully understand and master the relationship between ultrasonic grain scattering and the crystallographic and morphological characteristics…

Theoretical and numerical comparison of the elastic ultrasonic wave scattering in polycrystalline materials with fiber texture

The physics of the elastic ultrasonic wave scattering is of interest for the non-destructive Laser-Ultrasonics (LU) technique to characterize polycrystalline materials. Generally, polycrystalline media are composed of multiple anisotropic single…

Stress intensity factor determination along a kinked crack path by DIC analyses

Sharp kinks may be observed under shear loading or in materials containing weak directions, such as those produced by additive manufacturing. A better understanding of the fracture of these materials, both theoretically and experimentally, is…

Condition d'intégrabilité d'une loi d'hypoélaticité

Nous proposons une reformulation géométrique de l'hypoélasticité en terme de 1-formes (puissances) sur la variété des métriques riemanniennes. A partir de cette reformulation, nous établissons une nouvelle condition nécessaire d'intégrabilité d'une…

Augmented DIC and FE Analyses: A Two-Field Approach to Damage Localization

The prediction of localized phenomena is still challenging. In particular, running an entirely consistent simulation with experimental observations is delicate. It is proposed that FE simulations on fine meshes be augmented with experimentally…

Cinématiques des milieux généralisés et repères mobiles

This work presents a unified geometrical framework for modeling generalised continua in finite strains : in any dimension (rods, shells, 3D media), in any micromorphic theory of order one (micromorphic, Cosserat, micro-dilatation, etc) and in any…
