GPR-assisted evaluation of probabilistic fatigue crack growth in rib-to-deck joints in orthotropic steel decks considering mixed failure models

A State‐of‐Art Review on Prediction Model for Fatigue Performance of Welded Joints via Data‐Driven Method

“…[ 184 ] The hybrid model combining Gaussian regression and dynamic Bayesian network was established to estimate the probability S–N curve of welded joints. [ 185,186 ] As shown in Figure , the FEM model was integrated into the approximate Bayesian framework to realize the accurate prediction of fatigue reliability. [ 187 ] Fatigue reliability analysis model can be constructed via Latin hypercube sampling technology, SVM, and Monte Carlo (MC) simulations, which exhibited good accuracy and universality.…”

Mixed-mode fatigue crack propagation simulation by means of Geq and walker models of the structural steel S355

“…Yu et al [17] proposed a time-based fatigue crack growth method for steel bridges under traffic loading that does not require cycle counting. Heng et al [18] proposed a probabilistic fatigue crack growth (PFCG) model including toe-to-deck (TTD) cracking and root-to-deck (RTD) cracking under mixed failure modes. Li et al [19] simulated the fatigue crack propagation of CFRP repaired steel plates with inclined cracks based on FEM.…”
