Structural mechanics

Non-intrusive two-scale coupling strategy of non-compatible models for the tolerance analysis of composite structures to local features

Imperfection tolerance analysis in composite structures requires suitable computational strategies which can be easily integrated into the finite element codes commonly used in engineering. A surface coupling method of homogeneous and heterogeneous…

Modeling of the morphic effect using a 1st-order transitional magneto-elastic energy

The study takes place in the context of magneto-elastic coupling. A new magnetoelastic energy formulation is proposed at the magnetic domain scale in order to account for the non-linear and non-monotonous effect of stress on magnetization and…

Influence of biaxial stress on magnetostriction - experiments and modelling

The study takes place in the context of in-line non-destructive testing of steels and the development of magnetomechanical models that it requires. New magnetic and magnetostrictive measurements of a steel submitted to biaxial mechanical loading are…

Modelling of stator sheets punching effect on EV motor performances

The effect of punching of electric motor sheets on electrical machine performances is addressed. The approach is using measurement and modelling of mechanical stress effect on B(H) curves. A new coupled magneto-elastic Preisach model is proposed and…

Caractérisation et modélisation d'un alliage binaire Niobium-Titane

Dans cet article, nous présentons la caractérisation de fils de 26at%Nb-Ti. Présenté comme alliage à mémoire de forme, le matériau ne présente cependant pas d'émission de chaleur au cours d'une mesure de calorimétrie différentielle (DSC). L'absence…

Structural mechanics

Réseaux de neurones informés par la physique pour l’apprentissage de lois de comportement.

L’endommagement des structures mécaniques est une préoccupation permanente en ingénierie, liée à des problématiques de durabilité et de sécurité. La thématique est actuellement l’objet de diverses activité de recherche ; un exemple caractéristique…

Full-field displacement measurement method of metal-as-insulation pancake at liquid nitrogen temperature

In situ measurement of metal-as-insulation (MI) high temperature superconductor (HTS) pancake deformation gives insight to its actual mechanical state. Measurement of hoop strain for inner / outer turn of MI pancake is usually made by strain gauges…
