Title: | Modelling of the Mechanical Behaviour of Ultra-Fine Grained Titanium Alloys at High Strain Rates |
Language (ISO): | en |
Abstract: | Results of numerical simulations of the mechanical behaviour of coarse grained and UFG titanium alloys under quasi-static uniaxial compression and plane shock wave loading are presented in this paper. Constitutive equations predict the strain hardening behaviour, the strain rate sensitivity of the flow stress and the temperature softening of titanium alloys with a range of grain sizes from 20 µm to 100 nm. Characteristics of the mechanical behaviour of UFG a and a+ß titanium alloys in wide range of strain rates are discussed. |
