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 ... -
Communication avec acteABED-MERAIM, Farid; (Société Marocaine des Sciences Mécaniques, 2007)
Cette étude est consacrée à la stabilité de la réponse quasi-statique de systèmes standard dissipatifs (visco-élastiques, visco-plastiques ou élasto-plastiques). Dans le cas de solides visqueux (visco-élastiques ou ...

Parameter identification of advanced plastic potentials and impact on plastic anisotropy prediction Article dans une revue avec comité de lecture; ; ; ; ; ;BALAN, Tudor (Elsevier, 2009)
In the work presented in this paper, several strain rate potentials are examined in order to analyze their ability to model the initial stress and strain anisotropy of several orthotropic sheet materials. Classical quadratic ...

Article dans une revue avec comité de lectureBEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (Elsevier, 2015)
Localized necking is often considered as precursor to failure in metal components. In modern technologies, functional components (e.g., in flexible electronic devices) may be affected by this necking phenomenon, and to ...
