Overview

Randomized trial explores natural frequencies of porous functionally graded plates, indicating implications for engineering design.

Key Points

  • The research aims to analyze the natural vibration characteristics of porous functionally graded plates using a novel shape function approach.
  • Developed an analytical framework combining innovative shape functions and a porosity model within higher-order shear deformation theory.
  • Used power-law distributions for material properties and incorporated voids via a refined porosity formulation.
  • Applied the Navier technique to solve governing equations for simply supported plates and conducted a parametric study.
  • Demonstrated exceptional agreement with established theories on vibrational behavior.
  • Revealed significant relationships between power-law index, porosity distribution, and natural frequencies.
  • Provided insights into the coupled effects of these factors on vibrational characteristics.
