A critical plane-based high-cycle multiaxial fatigue criterion, known as the Carpinteri-Spagnoli (C-S) criterion, is here extended to evaluate the fatigue lifetime of plain metallic components under constant amplitude loading in the low/medium-cycle regime. An equivalent strain amplitude, computed through a quadratic combinations of strain components in the critical plane, is taken as the fatigue damage parameter. A validation by experimental data pertaining the biaxial fatigue of plain steel specimens underboth proportional and non-proportional loadings is performed.

Abstract

A critical plane-based high-cycle multiaxial fatigue criterion, known as the Carpinteri-Spagnoli (C-S) criterion, is here extended to evaluate the fatigue lifetime of plain metallic components under constant amplitude loading in the low/medium-cycle regime. An equivalent strain amplitude, computed through a quadratic combinations of strain components in the critical plane, is taken as the fatigue damage parameter. A validation by experimental data pertaining the biaxial fatigue of plain steel specimens underboth proportional and non-proportional loadings is performed.
