A generalized energy-based fatigue–creep damage parameter for life prediction of turbine disk alloys (2012, background): “2) beyond necking was found to be the upper bound for the true stress–strain relation [27].”
Characterization of the post-necking strain hardening behavior using the virtual fields method (2013, methodology): “However, accurate measurements of the evolving geometries such as curvature radius and rectangular cross-sectional area are not easy tasks in practice (Ling, 1996; Cabezas and Celentano, 2004).”
Identification of plastic constitutive parameters at large deformations from three dimensional displacement fields (2011, unknown): “The comparison can be made either on the force measured during the test [27,28] or including also the displacement measured at the surface of the specimen, for instance using full-field measurements [22,26].”
Experimental and numerical analysis of the tensile test using sheet specimens (2004, background): “Diffuse necking has been developed for both types of samples (localized necking is only observable for very thin strips; see Ling, 1996).”
The Chaboche nonlinear kinematic hardening model: calibration methodology and validation (2008, methodology): “The experimental effort is thus much greater than for monotonic loading where the simple isotropic model is broadly used and can be tuned using standard tensile tests [5].”
