Identification of post-necking stress–strain curve for sheet metals by inverse method
110
TL;DR: In this article, the authors presented a method for obtaining the flow curve of sheet metals over a large range of strain through the combination of simple tensile test and finite element analyses, and evaluated different hardening functions for their capabilities in approximating the entire flow stress curves up to localized necking.

Large strain deformation of polycrystalline metals at low homologous temperatures
J.E. Hockett,O.D. Sherby +1 more
TL;DR: In this paper, large strain compression data (true strains to about −3.0) were presented for polycrystalline α U and α Fe at room temperature, together with other published data at low homologous temperatures (≈0.2 Tm), where Tm is the absolute melting temperature, suggest that a steady-state flow stress σs is approached after extensive strain-hardening.
