Area of Science:

  • Biomedical Engineering
  • Solid Mechanics
  • Cardiovascular Physiology

Context:

  • Accurate assessment of myocardial elasticity is vital for diagnosing cardiac conditions.
  • Existing methods for elasticity measurement can be invasive or complex.
  • The Advani-Lee equation offers a theoretical basis for non-invasive elasticity estimation.

Purpose:

  • To numerically solve the Advani-Lee equation for free vibrations of fluid-filled spherical shells.
  • To validate the derived equation (E = 86.5.a².f²) against experimental data.
  • To determine myocardial elasticity in normal subjects using a simplified Advani-Lee equation.

Summary:

  • Numerical solutions of the Advani-Lee equation were obtained for fluid-filled spherical shells.
  • Experimental validation using silicone rubber shells showed excellent agreement between the Advani-Lee equation and standard stretch tests.
