Journal ArticleDOI
Predictions of forming limit diagrams using a rate-dependent polycrystal self-consistent plasticity model
TL;DR: In this paper, a self-consistent approach has been introduced to simulate the polycrystal FLD behavior, including the effects of slip hardening, strain-rate sensitivity, anisotropy and initial texture.
Journal ArticleDOI
Structural reactivation in plate tectonics controlled by olivine crystal anisotropy
Andréa Tommasi,Mickael Knoll,Mickael Knoll,Alain Vauchez,Javier Signorelli,Catherine Thoraval,Roland E. Logé +6 more
TL;DR: In this paper, the authors point to mechanical anisotropy arising from the inherited orientation of crystals of the mineral olivine in the lithospheric mantle as the cause of this behaviour.
Journal ArticleDOI
Influence of grain shape on the planar anisotropy of rolled steel sheets ― evaluation of three models
TL;DR: In this paper, the plastic anisotropy of textured polycrystalline aggregates is investigated using three micro-macro averaging schemes: a crystal plasticity based finite element model (CPFEM), the viscoplastic self-consistent (VPSC) scheme of Lebensohn and Tome, and a multisite model that is based on a simplified treatment of the interaction of adjacent grains.
Journal ArticleDOI
Activated slip systems and microcrack path in LCF of a duplex stainless steel
Maria-Cecilia Marinelli,Ahmed El Bartali,Javier Signorelli,Pierre Evrard,Véronique Aubin,I. Alvarez-Armas,Suzanne Degallaix-Moreuil +6 more
TL;DR: In this article, a low-cycle fatigue test was carried out at room temperature on a forged duplex stainless steel type 25-07 alloyed with 0.17% nitrogen, and activated slip systems were identified in austenite and ferrite, respectively.
Journal ArticleDOI
Calculation of intergranular stresses based on a large-strain viscoplastic self-consistent polycrystal model
TL;DR: In this article, an extension of the viscoplastic self-consistent (VPSC) polycrystal model for the calculation of the intergranular Cauchy stresses in an aggregate is presented.
