Assessment Of Fatigue Crack Propagation Life Based On Physics-Informed Neural Networks Under Ensemble Learning In Hydrogen Environments

Hydrogen storage and transport systems use pipeline steel, where hydrogen embrittlement accelerates fatigue crack propagation and reduces service life. Accurate life evaluation is necessary for safe operation. Conventional approaches experimental fatigue testing, finite-element simulation, and empirical laws such as...

A dual-descent adaptive control method for reliability-based design optimization

Time-Variant Reliability Analysis via Copula Failure Correlation and Advanced Kriging

In practical engineering, mechanical structures are affected by time-dependent uncertainties and by correlated failure modes. This study proposes an enhanced time-variant reliability analysis framework by coupling a mixed Archimedean Copula model with an adaptive Kriging model driven by the maximum expected prediction...
