[en] The aim of this study is to present a new multiaxial fatigue model based on
phenomenological approach for the proportional loading. The model estimations are compared to the classical Lemaitre-Chaboche [1] fatigue model and experimental results. The comparison is done by simulation of SN curves of notched and un-notched forged TA6V samples. To take into account the effect of stress gradient near notch root, the applied loads such as stress amplitude and Von Mises stress are affected by the triaxialty function introduced by Lemaitre [2]. The models enhanced by triaxialty function give correct results for life estimation of notched samples.
