In the present paper, the capability of two multiaxial fatigue criteria in both estimating the fatigue life and predicting the crack initiation path of metallic components under random loading is investigated. As a matter of fact, it is very difficult to find in the literature the predicted crack initiation path data when the loading has a random nature. To such an aim, an experimental campaign performed at the Opole University of Technology on a construction steel 10HNAP, under biaxial non-proportional random loading, is simulated by means of both a time-domain criterion and a frequency-domain one.

Abstract
In the present paper, the capability of two multiaxial fatigue criteria in both estimating the fatigue life and predicting the crack initiation path of metallic components under random loading is investigated. As a matter of fact, it is very difficult to find in the literature the predicted crack initiation path data when the loading has a random nature. To such an aim, an experimental campaign performed at the Opole University of Technology on a construction steel 10HNAP, under biaxial non-proportional random loading, is simulated by means of both a time-domain criterion and a frequency-domain one.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
