Abstract
This study presents an automated computational framework for simulating three‐dimensional (3D) fatigue crack growth and adhesive delamination in carbon fiber‐reinforced polymer (CFRP)‐strengthened steel tubular T‐joints. The model integrates continuum damage mechanics with the extended finite element method (CDM‐XFEM) to concurrently simulate progressive damage in the steel substrate and failure at the bonded interfaces. A Python‐driven interface automates the cycle‐by‐cycle simulation of crack propagation, material degradation, and selective element deactivation in a finite element programme. Validation is performed using results from high‐cycle out‐of‐plane bending (OPB) fatigue tests. Furthermore, fracture surface morphologies predicted by the model are compared with experimental data acquired from noncontact 3D laser scanning of the tested specimens. The results demonstrate that the framework provides accurate predictions for fatigue life, crack trajectories, debonding zones, and crack growth rates, with deviations of less than 6% in fatigue life and under 1.4 mm in fracture surface geometry.
This study experimentally and numerically investigates fatigue damage in additively manufactured 316L stainless steel produced by selective laser melting using the powder bed fusion–laser beam process. More than 100 specimens were tested under tensile and strain‐controlled fatigue loading to evaluate the effects of s...

Wind turbine main‐bearing crack assessment requires consistent treatment of material crack growth and operating‐load uncertainty. Fatigue crack‐growth tests were performed on GCr15 0.5‐T CT specimens at , 0.10, and 0.50, and Paris parameters were identified. Finite element simulation at agreed with experiments within...

This study investigated the fatigue behavior of 2050‐T8 Al–Li alloy containing dual corrosion pits. Full‐field strain maps, damage severity factor curves, and fractographic analysis were integrated to characterize fatigue damage evolution, microcrack nucleation, and propagation under varying stress levels and pit dis...

A unified thermomechanical fatigue (TMF) life-prediction methodology is presented for lamellar graphite (grey) cast iron brake rotors operating under the severe transient thermal loads that arise in brake dynamometer durability testing. The workflow links four ingredients within a single rotor-level framework: transien...
