CHATZIGEORGIOU, George; MERAGHNI, Fodil (Elsevier BV, 2022-12)
This paper presents for the first time an extended Mori-Tanaka approach aimed at identifying the little-explored piezoelectric response of unidirectional nanoporous composites with energetic surfaces. The interface is ... -

The formation of a white etching layer (WEL), a very hard and brittle phase on the rail surface, is associated with a progressive transformation of the pearlitic grain to very fragmented grains due to the cumulative passage ...

Study of the Influence of Cutting Edge on Micro Cutting of Hardened Steel Using FE and SPH Modeling Article dans une revue avec comité de lecture; ; ; ; ; ; ; ;D’ACUNTO, Alain (MDPI, 2022-07)
Micromachining allows the production of micro-components with complex geometries in various materials. However, it presents several scientific issues due to scale reduction compared to conventional machining. These issues ...
