Webviscoplastic approximation to crystal plasticity (Asaro and Needleman, 1985) is available (Lebensohn, 2001; Lebensohn et al., 60 R.A. Lebensohn et al./International Journal of Plasticity 32–33 (2012) 59–69. 2008, 2009; Lee et al., 2011). Under this approximation, the elastic strains are considered negligible compared with the plas-

WebNov 1, 2024 · In this work, a crystal plasticity lattice particle method (CPLPM) is proposed and verified for modeling the plastic deformation of single cubic crystals. The proposed CPLPM takes full advantage of the lattice rotation scheme in representing material anisotropy using the lattice structure rather than stiffness transformation.
