BEN BETTAIEB, Mohamed; ; ABED-MERAIM, Farid (SAGE Publications, 2024-12)
In this work, experimental tests and numerical simulations are carried out to investigate the buckling behavior and failure modes of auxetic cellular structures and sandwich panels with auxetic cores. Different Poisson's ... -

Article dans une revue avec comité de lecturePELTIER, Laurent; ; MERAGHNI, Fodil; ; LAHEURTE, Pascal; BERVEILLER, Sophie (Springer Science and Business Media LLC, 2022-08)
In this work, a new class of iron-based high entropy shape memory alloys (HE-SMAs) have been designed, characterized, and optimized. These FeCu-NiMnV alloys (FeMn-like) with damping properties at low and high temperatures ...

We present a novel elasticity-inspired data-driven Fourier homogenization network (FHN) theory for periodic heterogeneous microstructures with square or hexagonal arrays of cylindrical fibers. Towards this end, two ...
