MULTIAXIAL FATIGUE OF A RAILWAY WHEEL STEEL
Uniaxial and biaxial torsional fatigue specimens were extracted from a railway wheel steel. The fatigue tests were performed with the stress ratio of R= -1 by using uniaxial and biaxial torsional fatigue test specimens at room temperature in air. The ultimate and yield strengths of the steel were ev...

| description | Uniaxial and biaxial torsional fatigue specimens were extracted from a railway wheel steel. The fatigue tests were performed with the stress ratio of R= -1 by using uniaxial and biaxial torsional fatigue test specimens at room temperature in air. The ultimate and yield strengths of the steel were evaluated. The uniaxial
fatigue limit was 422.5 MPa, which corresponds to 67% of the ultimate tensile strength. The ratio of e e / was 0.63. Appropriate parameters to predict the fatigue life of the steel under multiaxial stress states were reviewed. |
