This work presents a new micromechanical fatigue damage model for reinforced thermoplastic composites. The study aims at modeling high cycle fatigue damage of a short glass fiber reinforced polyamide-66. The developed ... -
Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid (Trans Tech Publications, 2015)
Thin structures are commonly designed and employedin engineering industries to save material, reduce weight and improve the overall performance of products. The finite element (FE) simulation of such thin structural ...

Article dans une revue avec comité de lecture;CHALAL, Hocine; ABED-MERAIM, Farid; BALAN, Tudor (Trans Tech Publications, 2012)
In this work, we propose to couple the Gurson-Tvergaard-Needleman (GTN) model, known for its widespread use to describe damage evolution in metallic materials, to the Rice localization criterion. ...

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 ...

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 ...

Micromechanics-Based Damage Analysis of Fracture in Ti5553 Alloy with Application to Bolted Sectors Article dans une revue avec comité de lectureBEN BETTAIEB, Mohamed; ; ; ; ; ; (Springer Verlag/ASM International, 2015)
A physics-based, uncoupled damage model is calibrated using cylindrical notched round tensile specimens made of Ti5553 and Ti-6Al-4V alloys. The fracture strain of Ti5553 is lower than for Ti-6Al-4V in the full range of ...

Conférence invitée; ;MERAGHNI, Fodil (SPIE, 2014)
In this work, a constitutive model is developed that describe the behavior of shape memory alloys undergoing a large number of cycles, developing internal damage, and eventually failing. Physical mechanisms associated with ...
