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

Autor: Jindong Jiang, Jiajun Wu, Qiang Chen, George Chatzigeorgiou, Fodil Meraghni

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 Deep Homogenization Network (DH

Gradient enhanced multi-scale modeling framework for glass fiber reinforced polyamides

Autor: Soheil Satouri, George Chatzigeorgiou, Adil Benaarbia, Fodil Meraghni

This study proposes a multi-scale gradient enhanced nonlocal modeling framework aimed at predicting the mechanical response of long glass fiber reinforced polyamide composites that exhibit nonlinear viscoelastic viscoplastic rheology with ductile dam

Extended mean-field homogenization of unidirectional piezoelectric nanocomposites with generalized Gurtin-Murdoch interfaces

Autor: Qiang Chen, George Chatzigeorgiou, Fodil Meraghni

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 simulated using the generalized

Recursive multiscale homogenization of multiphysics behavior of fuzzy fiber composites reinforced by hollow carbon nanotubes

Autor: Qiang Chen, Fodil Meraghni, George Chatzigeorgiou

Fuzzy fibers are fibers enhanced in terms of multiphysics properties with radially oriented carbon nanotubes grown on their surface through the chemical deposition process. For the first time, this paper attempts to present two generalized zeroth-ord
