An efficient time-domain fatigue analysis and its comparison to spectral fatigue assessment for construction steel 10HNAP

• The accuracy of two fatigue criteria for multiaxial random loading is discussed. Fatigue tests related to 10NHAP steel and available in the literature are simulated. lifetime crack initiation path estimated through present criteria. agreement between experimental data theoretical results satisfactory. compared with those determined three In paper, capability both estimating life predicting metallic components under investigated. As a matter fact, it very difficult find predicted when has nature. To such an aim, campaign performed at Opole University Technology on construction 10HNAP, biaxial non-proportional loading, simulated by means time-domain criterion frequency-domain one.
