Web27 de abr. de 2024 · Plastic flow localization is possibly induced by (i) the yield surface vertex effect [1, 2], (ii) dilatational plastic flow accompanying macroscopic softening due to evolving damage (nucleation and growth of voids) [3, 4], (iii) thermal softening in adiabatic or high-speed deformation , and (iv) deviations from the normality rule for plastic flow … Web24 de jun. de 2024 · Abstract. The standard viscous–plastic (VP) sea ice model with an elliptical yield curve and a normal flow rule has at least two issues. First, it does not simulate fracture angles below 30∘ in uni-axial compression, in contrast with observations of linear kinematic features (LKFs) in the Arctic Ocean. Second, there is a tight, but …
