Comparison of several models for the determination of the phase transformation yield surface in shape-memory alloys with experimental data

Proportional biaxial loadings (tension(compression)–internal pressure, bicompression) permit the experimental determination of the phase transformation yield surface in the stress space (e.g. the appearance of the martensitic phase inside the austenitic one). We review several theoretical, phenomenological and mathematical models which calculate the phase transformation yield surface obtained with multiaxial proportional loading experiments. We compare the predictions with experiments.
