Self-heating measurements under cyclic loadings allow for fast estimations of fatigue properties. These tests are performed under tension–torsion loadings on a medium-carbon steel and a model accounting for heterogeneities is proposed to analyse heat transfer results. Both proportional and non-proportional loading paths are predicted.
