Impact of guillotine cutting on losses in silicon steel

An experimental study of the impact of cutting processes on the magnetic properties of electrical steel sheets is presented. Cuttings by guillotine and electric discharge machining, with and without heat treatment, are considered. Microstructural…

Full magnetoelastic behavior of DP steel in biaxial mechanical loading condition -multiscale model

Advanced High Strength Steels (AHSS) raise a growing interest as weight saving solutions with high mechanical properties due to a complex (low scale and multiphased) microstructure. Adequate heat treatments of such alloys must be assessed in order…

Multi-instrumented in-situ strain induced martensitic transformation measurements of medium Mn stainless steels

The existence of an austenite-martensite phase transformation while undergoing plasticity gives excellent properties to unstable stainless steels (e.g. AISI 301 grades). Understanding and monitoring this phenomenon is essential for the development…

Identification de paramètres d'un modèle d'endommagement. Influence des conditions aux limites.

Calibration of damage models for cementitious materials using the Finite-Element Model Updating (FEMU) method often relies on simplifying assumptions regarding boundary conditions, which are difficult to measure with local sensors. This study…

Modélisation avancée des tsunamis : une approche spectrale pour intégrer la dynamique sismique

Malgré les progrès en modélisation des tsunamis, certains événements historiques restent mal compris. Notamment, la dynamique du mouvement sismique est souvent négligée, les perturbations étant modélisées par un déplacement instantané du fond marin…

A two-node nonlinear connector for simulating simplified models of bolted joints under extreme loads

Abstract In industrial applications, fine-scale simulations of bolted joints are often impractical due to the numerous nonlinearities in the vicinity of the bolt, which result in computationally expensive calculations, particularly during the early…

Stability of propagating Austenite-Martensite interface in Ni-Mn-Ga single crystal

The transformation between the austenite and martensite phases in Shape Memory Alloys (SMAs) occurs via the nucleation and propagation of an Austenite-Martensite interface (A-M interface), whose morphology/configuration determines the driving force …
