However, the substantial computational demands of CPFEM limit its practical application in investigating the sample size effect on maximum FIPs. This study employs the recently developed Deep Symbolic Regression (DSR) algorithm to generate interpretable expressions linking sample size with the statistical characteristics of maximum FIPs in duplex Ti–6Al–4 V with random texture.

The strong agreements found between DSR and EVT expressions not only validates the mathematical underpinnings of EVT but also demonstrates how EVT can elucidate the physical insights revealed by DSR. Building on this, we introduce a novel method, i.e., Regrouping of Maximum FIPs (RMF), to improve prediction reliability by mitigating the influence of the threshold <em>x</em><sub>0</sub> in EVT.

The results revealed that the dovetail assembly gradually exhibited a sticking phenomenon, stabilizing after approximately 10,000 cycles, with relative slip significantly reduced compared to the initial cycles. Surface wear and temperature were also monitored. The findings showed that during the fretting tests, a considerable amount of wear debris accumulated in the contact zone, increasing the coefficient of friction (COF) and intensifying the sticking phenomenon. This led to reduced frictional energy, causing minimal changes in surface temperature. Consequently, for fretting fatigue in dovetail assemblies, localized stress concentration emerged as the primary factor affecting fatigue life, surpassing influences from relative slip, surface wear, and frictional heat generation. Additionally, a finite element model of the dovetail assembly was developed, incorporating the Chaboche material constitutive model to calculate the stable stress–strain distribution under cyclic loading. The model’s predictions were validated against the DIC test results. Based on an established multiaxial fatigue framework, a program was developed to post-process the simulation results, producing diagrams for critical angles and damage distribution.

The fatigue behavior of DI was assessed under both torsion fatigue and RCF. The RCF of DI was assessed by a 3 ball-on-rod test rig at a peak pressure of 3.6 GPa. Torsion fatigue tests were performed using an MTS test setup to determine the material’s stress-life (S-N) response. A Rockwell hardness tester was utilized to determine the global hardness of DI materials, while a nano indenter was employed to obtain the hardness distribution along the depth of the DI RCF rods. X-ray diffraction (XRD) was employed to measure the residual stresses prior to and after RCF testing to assess the effect of residual stresses on fatigue life.

The material constants used in the damage evolution equation of the CDM framework were obtained using torsion fatigue S-N data. Different residual stress profiles as a function of the depth of the material were incorporated into the model, and the corresponding RCF life predictions were evaluated. The analytical results demonstrated good corroboration with the experimental results, confirming the significance of residual stress in influencing fatigue performance.
