Purpose Engineering components/structures with geometric discontinuities normally bear
complex and variable loads, which lead to a multiaxial and random/variable amplitude …

In this paper, a comparative review between time-and frequency-domain methods for fatigue
damage assessment is performed. The principal steps of a fatigue study are described in …

A novel deep learning approach is established in this work to directly model the highly
nonlinear mapping between the complex loading conditions (input) and the multiaxial …

In this study, a physics-informed neural network (MFLP-PINN), combining multiaxial fatigue
critical plane model and the neural network, is proposed for life prediction. First, a multiaxial …

Modeling of vibration fatigue of welded structures in the frequency domain can be
particularly challenging. For instance, the stress singularity at weld locations causes finite …

The frequency domain techniques (also known as “spectral methods”) prove significantly
more efficient than the time domain fatigue life calculations, especially when they are used …

Notched components with complex configurations are normally designed for engineering
functional requirements. Geometrical discontinuities generally result into stress …

Aero engine components like compressor discs normally operate under harsh conditions
like complex multiaxial stress states. Notch effect is often critical for structural integrity …

The irregularity of peak and valley stress values of loading histories is the main impediment
for accurate fatigue‐based structural health monitoring. Since the available fatigue material …

A data-driven approach to modeling multiaxial fatigue in frequency domain is proposed. The
paper presents a methodology through which models can be built to predict fatigue damage …
