dc.description.abstractThe aim of this investigation was to develop a method for the prediction of the high strain multiaxial fatigue life (low cycle fatigue) of a steel, based on high strain uniaxial stress fatigue data. In this study, thin walled cylindrical specimens were subjected to fully reversed high biaxial strains using differential pressure and axial load. The directions of the principal strains were maintained parallel and perpendicular to the specimen axes. Five different strain ratios were investigated covering both the in phase and fully out-of-phase conditions. The material selected for this investigation was a medium carbon steel; C-1018. It was round that a maximum principal strain theory, based on the plastic components of the applied strains, taking into account the strain in the thickness direction, resulted in a correlation between the biaxial and uniaxial results which was either good or conservative.
