Based on Bain's principle, a C1‐continuous thermo‐mechanical micro‐macro constitutive model for martensitic phase transformation (PT) of monocrystals at finite strains and hyperelastic free energy function is used. It is represented by a unified non‐convex Lagrangian variational functional. The convexification problem is solved here by generalizing the explicit form of the lower Reuss bound for small strains given in [1] to finite strains. Abaqus is used for implementation of 3D finite elements in space, via UMAT‐interface which requires Jaumann rate of Kirchhoff stress tensor. Deterministic validation of the model is presented by comparing verified numerical results with experimental data for Cu82Al14Ni4[6] for quasiplastic PT. (© 2008 WILEY‐VCH Verlag GmbH & Co.
