摘要: Abstract Viscoplastic constitutive models are used for crystals subjected to large strains and high strain-rates; they based on the assumption that plastic strain occurs by viscous crystallographic slip. Rate-sensitivity strain-rate effects shears lattice rotations investigated; it is shown sensitivities such as those observed at very rates temperatures may increase total number of significantly active slip systems decrease amount spin. This leads contrasted texture evolutions in tension simple shear which described.
