ABED-MERAIM, Farid; ; (2015)
Cette contribution porte sur la prédiction de la striction diffuse dans le contexte des tôles métalliques sous changements biaxiaux. A cette fin, deux approches sont considérées, à savoir la théorie de bifurcation et le ... -

In this work, a new physically stabilized and locking-free formulation of the SHB8PS element is presented. This is a solid-shell element based on a purely 3D formulation. It has eight nodes as well as five integration ...

Formulation of new quadratic solid-shell elements and their evaluation on popular benchmark problems Communication sans acte;ABED-MERAIM, Farid; (2010)
Over the last decade, considerable progress has been made in the development of three-dimensional finite elements capable of modeling thin structures. The coupling between solid and shell formulations has proven to be an ...

Article dans une revue avec comité de lecture; ;BALAN, Tudor (Elsevier, 2009)
This paper reviews a class of anisotropic plastic strain-rate potentials, based on linear transformations of the plastic strain-rate tensor. A new formulation is proposed, which includes former models as particular cases ...

For numerical simulation of sheet metal forming, more and more advanced phenomenological functions are used to model the anisotropic yielding. The latter can be described by an adjustment of the coefficients of the yield ...

A physically based elasto-visco-plastic constitutive model is presented and compared to experimental results for three different mild steels. The experiments consist of tensile tests ranging from quasi-static conditions ...
