CHALAL, Hocine; ABED-MERAIM, Farid (Luso Impress S.A. Publisher, 2015)
A family of prismatic and hexahedral assumed-strain based solid–shell elements (SHB elements), with their linear and quadratic versions, are presented in this work to model thin structures. These SHB elements are based on ... -

The deep drawing is one of the widely used processes in industry to give suited forms to metal sheets. During deformation the sheet and tools undergo high stresses. The sheet must carry on the deformation until the end of ...

Necking limit prediction in thin substrate-supported metal layers, used as functional components in electronic devices, represents nowadays an ambitious challenge. The aim of this work is to investigate the effect of ...

The elastic-plastic behavior of polycrystals is studied. A single-crystal constitutive law is defi ned thanks to crystalline plasticity in the large strain framework. The self-consistent scheme is adopted to obtain macroscopic ...

Deep drawing is a forming process widely used to obtain parts of suited shape from sheets initially flat. These sheets are obtained generally by rolling and thus present an initial orthotropic anisotropy. Several behaviour ...

In this work, two numerical ductile fracture criteria based on finite element (FE) simulations are proposed for the prediction of ductile fracture limits (DFLs) for sheet metals. An elastic–plastic model coupled with the ...
