The strain-induced α → ω phase transformation (PT) in a zirconium sample under compression and torsion under fixed load is investigated using the finite-element method (FEM), and results are compared to those for a sample in a diamond anvil cell (DAC) and a rotational diamond anvil cell (RDAC). Highly heterogeneous fields of stresses, strains, and concentration of the high-pressure phase are presented and analyzed. Some experimentally observed effects are analyzed and interpreted.
