he topic of material fatigue holds significant importance within both the scientific and industrial communities ([1]– [4]). The majority of component failures during service can be attributed to fatigue failure ([5]–[7]), presenting a major design challenge due to the complexities associated with real-world applications, including variable amplitude, randomness, multiaxiality and residual stresses ([8]–[13]).
