Constitutive characterization of a rare-earth magnesium alloy sheet (ZEK100-O) in shear loading: Studies of anisotropy and rate sensitivity
Abedini, Armin; Butcher, Clifford; Nemcko, Michael J.; Kurukuri, Srihari; Worswick, Michael J. (Elsevier, 2017-08-01)Rare-earth magnesium alloys such as ZEK100-O offer improved ductility over other conventional magnesium alloys at room temperature; however, they exhibit significant anisotropy and complex yield behaviour. In this work, a ... -
Evaluation and calibration of anisotropic yield criteria in shear Loading: Constraints to eliminate numerical artefacts
Abedini, Armin; Butcher, Clifford; Rahmaan, M. Taamjeed; Worswick, Michael J. (Elsevier, 2017-06-24)Many anisotropic phenomenological yield functions have been proposed in the literature in which their predictive capabilities strongly depend on the experimental calibration data as well as the calibration procedure to ... -
Experimental fracture characterisation of an anisotropic magnesium alloy sheet in proportional and non-proportional loading conditions
Abedini, Armin; Butcher, Clifford; Worswick, Michael J. (Elsevier, 2018-07)A comprehensive experimental investigation was performed to characterize the fracture behaviour of a rare-earth magnesium alloy sheet, ZEK100-O, under both proportional and non-proportional loading conditions. This material ... -
Fracture Characterization of Rolled Sheet Alloys in Shear Loading: Studies of Specimen Geometry, Anisotropy, and Rate Sensitivity
Abedini, Armin; Butcher, Clifford; Worswick, Michael J. (Springer, 2017-01-01)Two different shear sample geometries were employed to investigate the failure behaviour of two automotive alloy rolled sheets; a highly anisotropic magnesium alloy (ZEK100) and a relatively isotropic dual phase steel ...
