We propose to combine a physics-based finite element (FE) track model and a data-driven
Gaussian process regression (GPR) model to directly infer railpad and ballast stiffness from …

All structures exhibit some form of damping, but the characterization of damping is not well-
understood, and there is no universal damping model for the dynamic systems. Recently …

The finite element model updating is advantageous in damage identification because it is
physically meaningful and simultaneously identifies the damage location and extent. It …

Abstract A Frequency Response Functions (FRFs)‐based two‐step algorithm to identify
stiffness, mass, and viscous damping matrices is developed in this work. The proposed …
