PESCI, Raphaël (Elsevier, 2012)
This study presents a constitutive model for steels exhibiting SIMT, based on previous seminal works, and the corresponding methodology to estimate their parameters. The model includes temperature effects in the phase ... -
New prismatic solid-shell element: Assumed strain formulation and evaluation on benchmark problems Conférence invitée;ABED-MERAIM, Farid; (John F. ABEL and J. Robert COOKE / Internet-First University Press, 2008)
This paper presents the development of a six-node solid-shell finite element called (SHB6) and based on the assumed strain method adopted by Belytschko et al. [2]. It is integrated with a set of five Gauss points along a ...

Article dans une revue avec comité de lectureABED-MERAIM, Farid; (Wiley, 2009)
In this paper, the earlier formulation of the SHB8PS finite element is revised in order to eliminate some persistent membrane and shear locking phenomena. This new formulation consists of a solid-shell element based on a ...

The gain of productivity in machining is generally sought through tools and/or cutting conditions optimization however an increase in productivity is achievable too through the workmaterial optimization. The metallurgical ...

Article dans une revue avec comité de lecture;CHALAL, Hocine; BALAN, Tudor (Trans Tech Publications, 2012)
In this paper, we investigate the springback behavior of several advanced high-strength sheet steels (TRIP, Dual-Phase, ferrite-bainite) with thicknesses up to 4 mm. Samples were tested by means of the bending-under-tension ...

Communication sans acte;ABED-MERAIM, Farid; BALAN, Tudor (2010)
The originality of the approach used here is to present stability conditions of metallic materials modeled by general phenomenological laws and to apply them to the study of the formability of thin metallic sheets. The ...

Article dans une revue avec comité de lectureABED-MERAIM, Farid; BALAN, Tudor; (Springer Verlag, 2014)
The prediction of forming limit diagrams (FLDs) is of significant interest to the sheet metal forming industry. Although a large variety of plastic instability criteria have been developed during the previous decades, there ...
