Machine Learning‐Assisted Sensitivity Analysis for Stochastic Fatigue Life Modeling of Metals

International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 481-494, September 2025.
ABSTRACT Predicting fatigue life with precision requires more than isolated evaluations of mechanical properties; it requires an integrated approach that captures the interdependencies between various parameters, including elastic modulus, tensile strength, yield strength, and strain‐hardening exponent.

Effects of Shot‐Blasting and Induction Hardening on the Fatigue Strength of Hot‐Forged Wheel Bearing Hubs

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 8, Page 3353-3367, August 2025.
ABSTRACT Hot‐forged wheel bearing hubs are manufactured using a complicated fabrication process chain to obtain the desired microstructure and mechanical properties in different zones that experience varying local stress states. The different process steps modify the surface roughness and the residual stresses distribution and therefore affect the ...
