PESCI, Raphaël (Elsevier, 2020)
Wire-arc additive manufacturing has become an alternative way to produce industrial parts. In this work 15 kg walls are built with an effective building rate of 4.85 kg/h using an ER100 wire providing good tensile properties ... -

This paper describes a new single-shear specimen (SSS) and method to characterize the dynamic shear behavior of bulk metals using a traditional Split Hopkinson Pressure Bar (SHPB). By this method, the shear behavior of ...

Article dans une revue avec comité de lectureCHALAL, Hocine; ABED-MERAIM, Farid (World Scientific Publishing, 2019)
In this work, nonlinear dynamic analysis of thin structures is investigated using quadratic solid–shell (SHB-EXP) elements. The proposed SHB-EXP elements are based on a fully three-dimensional formulation using an in-plane ...

Strain-path dependent hardening models with rigorously identical predictions under monotonic loading Article dans une revue avec comité de lecture; ;BAUDOUIN, Cyrille; CHALAL, Hocine; BALAN, Tudor (Elsevier, 2021)
Accurate sheet metal simulation often requires advanced strain-path dependent material models, in order to predict the material response under complex loading conditions, including monotonic, reverse and orthogonal paths. ...

In the present contribution, a two-surface plasticity model is coupled with several diffuse and localized necking criteria to predict the ductility limits of hexagonal closed packed sheet metals. The plastic strain is ...

Communication avec acte; ;AYED, Yessine; ; ; GERMAIN, Guénaël (Elsevier BV, 2020)
Surface integrity induced by machining process affects strongly the performance of functional products, for instance, the fatigue life as well as the resistance to stress corrosion cracking. Consequently, it is relevant ...
