CHALAL, Hocine; ABED-MERAIM, Farid (Univerza v Ljubljani Fakulteta za strojništvo, 2017)
A family of prismatic and hexahedral solid–shell (SHB) elements, with their linear and quadratic versions, is proposed in this work to model thin structures. The formulation of these SHB elements is extended to explicit ... -
Ouvrage scientifique; ; ;MERAGHNI, Fodil (ISTE-Elsevier, 2018)
This book presents theoretical and numerical tools for studying materials and structures under fully coupled thermomechanical conditions, with a special focus on composites. The authors cover many aspects of the modeling ...

In this paper, the conditions for the occurrence of diffuse and localized necking in thin sheet metals are investigated. The prediction of these necking phenomena is undertaken using an elastic‒plastic model coupled with ...

In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ...

In this work, we propose two prismatic piezoelectric solid–shell elements based on fully three-dimensional kinematics. For this purpose, we perform electromechanical coupling, which consists in adding an electrical degree ...
