Crystal Plasticity Modelling of Large Strain Deformation in Single Crystals of Magnesium
(University of Waterloo, 2010-10-21)Magnesium, with a Hexagonal Close-Packed (HCP) structure, is the eighth most abundant element in the earth’s crust and the third most plentiful element dissolved in the seawater. Magnesium alloys exhibit the attractive ... -
Efficient fast Fourier transform-based numerical implementation to simulate large strain behavior of polycrystalline materials
(Elsevier, 2017-07-04)In this paper, a new full-field numerical framework is proposed to model large strain phenomena in polycrystals. The proposed framework is based on the elasto-viscoplastic (EVP) fast Fourier transform (FFT) formulation ... -
A new crystal plasticity framework to simulate the large strain behaviour of aluminum alloys at warm temperatures
(Elsevier, 2018-06-06)To improve metal formability, high temperature forming has become a desired manufacturing process. Phenomenological plasticity models are widely used in this application, however lack good predictive capability concerning ... -
Strain rate sensitivities of deformation mechanisms in magnesium alloys
(Elsevier, 2018-08-01)Strain rate sensitivity (SRS) is an important material property that governs the rate dependent mechanical behaviors associated with deformation rate changes, creep, stress relaxation, formability, etc. The variety of ...
