A Multi-Phase Equation of State and Strength Model for Tin
- AWE, Aldermaston, Reading, RG7 4PR (United Kingdom)
This paper considers a multi-phase equation of state and a multi-phase strength model for tin in the {beta}, {gamma} and liquid phases. At a phase transition there are changes in volume, energy, and properties of a material that should be included in an accurate model. The strength model will also be affected by a solid-solid phase transition. For many materials there is a lack of experimental data for strength at high pressures making the derivation of strength parameters for some phases difficult. In the case of tin there are longitudinal sound speed data on the Hugoniot available that have been used here in conjunction with a multi-phase equation of state to derive strength parameters for the {gamma} phase, a phase which does not exist at room temperature and pressure.
