Overview

Randomized trial investigates vibration behavior in stepped sandwich cylinders, indicating design implications.

Key Points

  • The study aims to investigate the free vibration behavior of stepped sandwich cylinders with auxetic honeycomb cores.
  • Developed formulations based on first-order shear deformation theory.
  • Applied the Rayleigh–Ritz method with boundary enforcement through Lagrange multipliers.
  • Implemented a one-dimensional ring finite element for numerical modeling.
  • Confirmed accuracy and reliability of formulations through comparison with literature.
  • Increasing inclination angle and relative thickness reduces the natural frequencies.
  • Higher core-to-face sheet thickness ratio generally lowers frequencies.
