  On elastic gaps in strain gradient plasticity: 3D discrete dislocation dynamics investigation 

  Article dans une revue avec comité de lecture

  AMOUZOU-ADOUN, Yaovi Armand; JEBAHI, Mohamed; FIVEL, Marc; FOREST, Samuel; LECOMTE, Jean-Sebastien; SCHUMAN, Christophe; 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 ...

  Coupled effects of crystallographic orientation and void shape on ductile failure initiation using a CPFE framework 

  Article dans une revue avec comité de lecture

  ZHU, Jianchang; BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid ; HUANG, M.S.; LI, Z.H. (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 ...

  Corrugation Reinforced Architectured Materials by Direct Laser Hardening: A Study of Geometrically Induced Work Hardening in Steel 

  Article dans une revue avec comité de lecture

  WANG, Zhige; BOUAZIZ, Olivier; 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 ...

  Thermally-activated hardening recovery in viscoplastic materials with kinematic hardening at high temperatures 

  Article dans une revue avec comité de lecture

  THIERCELIN, Léo; PRAUD, Francis; MERAGHNI, Fodil; FLEURY, Eric (ELSEVIER, 2023-05)

  In this work, a new constitutive model is proposed to describe the thermally-activated hardening recovery mechanism in metallic materials. This model takes up the concept of hardening recovery variable, which is extended ...

  Physically informed deep homogenization neural network for unidirectional multiphase/multi-inclusion thermoconductive composites 

  Article dans une revue avec comité de lecture

  JIANG, Jindong; WU, Jiajun; CHEN, Qiang; CHATZIGEORGIOU, George; MERAGHNI, Fodil (Elsevier BV, 2023-05)

  Elements of the periodic homogenization framework and deep neural network were seamlessly connected for the first time to construct a new micromechanics theory for thermoconductive composites called physically informed ...
