Efficient fast Fourier transform-based numerical implementation to simulate large strain behavior of polycrystalline materials
Nagra, Jaspreet Singh; Brahme, Abhijit; Lebensohn, Ricardo; Inal, Kaan (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
Cyr, Edward D.; Brahme, Abhijit; Mohammadi, Mohsen; Mishra, Raja K.; Inal, Kaan (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 ...
