CHALAL, Hocine; ABED-MERAIM, Farid (Springer Verlag, 2020)
The scientific literature has shown the strong effect of void size on material response. Several yield functions have been developed to incorporate the void size effects in ductile porous materials. Based on the interface ... -

The prediction of the ductility limit of sheet metals during forming processes represents nowadays and ambitious challenge. To reach this goal, a new numerical approach, based on the loss of ellipticity criterion [1], is ...

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. ...
