title = "Calculation of the fatigue life of a surface-hardened shaft by the finite-element method",
abstract = "This report addresses the problems encountered in machine component design when the material properties vary in the load carrying cross-section and when purely elastic design is unsuitable that is when fatigue may be an imminent failure mechanism. The problem encountered is solved by an elasto-plastic finite-element calculation for the surface hardened cylindrical SAE shaft in bending, torsion and combined bending torsion. The effective plastic strains in the cross section of me shaft are calculated and the fatigue life of the shaft is predicted according to the local strain approach. The analysed shaft is surface hardened by induction heating, the hardness and other material properties thus varying between me core and the surface. The loading is bending or torsion. Only the monotonic first quarter cycle of me loading is calculated. The fatigue life is evaluated using the calculated effective plastic strain amplitude.",
