Le phénomène de localisation des déformations plastiques, qui apparait lors d’opérations de mise en forme des tôles, représente l’une des principales causes de rebut des pièces produites dans l’industrie. Plusieurs critères ... -
Parameter identification of advanced plastic potentials and impact on plastic anisotropy prediction Article dans une revue avec comité de lecture; ; ; ; ; ;BALAN, Tudor (Elsevier, 2009)
In the work presented in this paper, several strain rate potentials are examined in order to analyze their ability to model the initial stress and strain anisotropy of several orthotropic sheet materials. Classical quadratic ...

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 ...

Article dans une revue avec comité de lecture;BALAN, Tudor (Elsevier, 2013)
Modeling of ductile damage is generally done using analytical potentials, which are expressed in the stress space. In this paper, for the first time it is shown that strain rate potentials which are exact conjugate of the ...
