Multiaxial Fatigue of 16MnR Steel Available to Purchase

Uniaxial, torsion, and axial-torsion fatigue experiments were conducted on a pressure vessel steel, 16MnR, at room temperature. The uniaxial experiments were conducted using solid cylindrical specimens. Axial-torsion experiments employed thin-walled tubular specimens subjected to proportional and nonproportional loading. A critical plane multiaxial fatigue criterion recently developed was found to correlate well with all the experiments conducted for the material. In addition, the fatigue criterion correctly predicted the cracking behavior of the material subjected to different loading paths.
