Abstract The fatigue damage model based on theory of damage mechanics is capable of predicting the fatigue life under multiaxial loading. Meanwhile, the application of critical plane method ...
A new path‐independent multiaxial fatigue damage parameter σn*, which is defined as the largest normal stress range between adjacent turning points of the maximum shear stress on the critical plane ...
This paper focuses on a comparative study of the critical plane approach (CPA) and the dissipated energy approach (DEA) for multiaxial fatigue evaluation on an AISI 316L steel. It is a follow‐up ...
initiation for the fully reversed multiaxial fatigue loading. In this stress parameter, the shear stress amplitude and normal stress amplitude on the critical plane were combined with the variable coefficients ...
and the damage accumulation rule employed in the model . The conservatism and non‐conservatism of predicted lives are examined for some combinations of these variables. A new critical plane called the weight ...
Multiaxial fatigue life analysis of notched specimens is a critical issue for structural integrity design. However, there is still a lack of multiaxial fatigue life prediction models with coupled ...
. For whole local strain history, the plane with weight‐averaged maximum shear strain range is defined as the critical plane in this study. Based on the defined critical plane , a multiaxial fatigue damage model ...
at the dangerous point and the critical point. In addition, based on the idea of stress–distance normalization, a new stress gradient impact factor is defined and a new method for predicting the multiaxial fatigue ...
prediction for multiaxial low‐cycle fatigue failure under non‐proportional loading. The currently used critical plane models are a special and simple form of the new model . NOMENCLATURE b , c = fatigue ...
on the fatigue lives of structures. A critical plane model for multiaxial fatigue lives prediction is also proposed by using the proposed non‐proportional influencing factor to modify the Fatemi‐Socie model ...
