CHEN, Qiang; ; ; (Association pour les MAtériaux Composites (AMAC), 2023-07)
This work proposes a probabilistic micromechanics damage framework to predict the uniaxial and cyclic stress-strain response and progressive damage in random glass-reinforced polyamide composites. Motivated by different ... -
Communication avec acte(Association pour les MAtériaux Composites (AMAC), 2023-07)Afin d’apporter un maxinmun d’éléments de compréhension quant au comportement mécanique des composites thermoplastiques renforcés de fibres courtes, la présente contribution propose une démarche multi-échelle par champs ...

Article dans une revue avec comité de lectureSATOURI, Soheil; ; ; ; (Elsevier, 2023-07)
This work aims at identifying the behavior of polyamide 66 (PA66) under different Relative Humidity (RH) conditions using a phenomenological model that accounts for viscoelastic and viscoplastic rheology coupled to ductile ...

Ductility limit prediction for polycrystalline aggregates using a CPFEM-based multiscale framework Article dans une revue avec comité de lecture;BEN BETTAIEB, Mohamed; ; ABED-MERAIM, Farid (Elsevier BV, 2023-08)
The ductility of polycrystalline aggregates is usually limited by two main phenomena: plastic strain localization and void coalescence. The goal of this contribution is to develop a new multiscale framework, based on the ...

Article dans une revue avec comité de lecture;JEBAHI, Mohamed; ; ; ; ; ABED-MERAIM, Farid (Elsevier BV, 2023-04)
Although presenting attractive features in dealing with small-scale size effects, strain gradient plasticity (SGP) theories can lead to uncommon phenomena for some boundary value problems. Almost all non-incremental ...

Article dans une revue avec comité de lectureZHU, Jianchang; BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid ; ; (Elsevier BV, 2023-03)
Ductile failure reveals to be an anisotropic phenomenon, for which the proper mechanism has not been clearly addressed yet in the literature. In this paper, the effects of some key anisotropy factors on ductile failure ...

Article dans une revue avec comité de lecture; ;DIRRENBERGER, Justin; LAPOUGE, Pierre (Wiley - VCH Gmbh, 2023-03)
Improving the strength-to-ductility trade-off remains the prime driving force for the development of advanced high-strength steel. Traditionally research breakthroughs are focused on the microstructure and relative phase ...
