Multiaxial fatigue under variable amplitude loadings: review and solutions

International Journal of Structural Integrity, 2022
PurposeEngineering components/structures with geometric discontinuities normally bear complex and variable loads, which lead to a multiaxial and random/variable amplitude stress/strain state.

Curved fatigue crack growth prediction under variable amplitude loading by artificial neural network

, 2021
The focus of this study is to predict curved crack FCG failure under variable amplitude load effectively and accurately. Based on the artificial neural network (ANN) and FCG path/life prediction models, a numerical calculation method is designed.

Experimental study on fatigue performance of RC beams strengthened with CFRP under variable amplitude overload and hot-wet environment

Composite structures, 2020
Highway reinforced concrete (RC) bridges are generally served under hot-wet environment and vehicle overload in south China, which will cause great fatigue damage to the bridge structures.
