Article dans une revue avec comité de lecture(Elsevier, 2009)Sheet metal forming processes are commonly associated with strain-path changes in the material. Macroscopic softening/hardening transient effects can appear due to the plastic anisotropy induced by these deformation stages. ...

Article dans une revue avec comité de lecture(Viện Hàn Lâm Khoa học và Công nghệ Việt Nam, 2009)In this paper, the formulation of a new six-node solid–shell element denoted (SHB6) is proposed. This prismatic element is based on a purely three-dimensional approach, and hence has displacements as the only degrees of ...
-
Article dans une revue avec comité de lecture(Elsevier, 2007)In this paper, an extended version of Biot's differential equation is considered in order to discuss the quasi-static stability of a response for a solid in the framework of generalized standard materials. The same equation ...

Communication avec acte(Francisco Chinesta , Yvan Chastel and Mohamed El Mansori, 2011)Within the framework of sheet metal forming, the importance of hardening models for springback predictions has been often emphasized. While some specific applications require very accurate models, in many common situations ...

Article dans une revue avec comité de lecture(Wiley, 2008)Automotive industries are more and more subject to restrictive environmental constraints. Weight reduction of structures seems to be an interesting way to satisfy these requirements. This can be achieved either by using ...
-
Article dans une revue avec comité de lecture(Springer Verlag, 2008)This work aims to study the strain localization in different sheet metal forming processesby the finite element method using advanced behaviour models. In order to improve the prediction of the formability limit of sheets ...

Communication avec acte(ENIM Editions, 2010)This paper focuses on machinability especially in drilling. It is usually estimated experimentally based on thrust force and torque measurements, chip morphology analysis, surface quality and tool wear tests. A specific ...
