Ductility limit prediction using a GTN damage model coupled with localization bifurcation analysis Article dans une revue avec comité de lecture(Elsevier, 2014)Because the localization of deformation into narrow planar bands is often precursor to material failure, several approaches have been proposed to predict this phenomenon. In this paper, the Gurson–Tvergaard– Needleman (GTN) ...

Article dans une revue avec comité de lecture(Elsevier, 2015)Magnetic Shape Memory Alloys (MSMAs) have been the subject of much research in recent years as potential high-actuation-energy multifunctional materials. In this work we analyze coupled magneto-mechanical stability analysis ...
-
Article dans une revue avec comité de lecture(Springer, 2015)In the present study, a new transformation criterion that includes the effect of tension–compression asymmetry and texture-induced anisotropy is proposed and combined with a thermodynamical model to describe the thermomechanical ...
-
Article dans une revue avec comité de lecture(Elsevier, 2015)With the design of new devices with complex geometry and to take advantage of their large recoverable strains, shape memory alloys components (SMA) are increasingly subjected to multiaxial loadings. The development process ...
-
Article dans une revue avec comité de lecture(IOP Publishing, 2015)In the current manuscript, a homogenization framework is proposed for periodic composites with shape memory alloy (SMA) constituents under quasi-static thermomechanical conditions. The methodology is based on the step-by-step ...

Article dans une revue avec comité de lecture(Elsevier, 2014)This paper presents an identification procedure for the parameters of a thermodynamically based constitutive model for Shape memory Alloys (SMAs). The proposed approach is a gradient-based method and utilizes an analytical ...

Article dans une revue avec comité de lecture(Elsevier, 2015)In this paper we present an internal variable-based homogenization of a composite made of wavy elastic-perfectly plastic layers. In the context of a strain-driven process, the macrostress and the effective yield surface ...
