Area of Science:

  • Solid Mechanics
  • Wave Propagation
  • Materials Science

Background:

  • Guided elastic waves are crucial for material characterization and non-destructive testing.
  • Understanding wave behavior in pre-stressed materials is essential for accurate analysis.

Purpose of the Study:

  • To investigate the propagation characteristics of guided elastic waves in a pre-stressed elastic compressible layer.
  • To analyze the influence of static pre-stress, material properties, and frequency on wave propagation.
  • To determine conditions under which guided wave propagation is not possible.

Main Methods:

  • Derivation of the explicit dispersion equation for guided elastic waves.
  • Analysis of the dispersion equation considering arbitrary strain energy functions for both layer and host materials.
  • Examination of equibiaxial in-plane deformations with common principal axes of strain.

Main Results:

  • The dispersion equation was derived in explicit form, enabling detailed analysis.
  • Wave propagation characteristics were found to be dependent on frequency, material, and stress parameters.
  • Specific combinations of these parameters were identified that inhibit guided wave propagation.

Conclusions:

  • The study provides a comprehensive understanding of guided elastic wave propagation in pre-stressed layered materials.
  • The findings are critical for designing and interpreting experiments involving pre-stressed elastic composites.
  • The identified conditions for non-propagation offer insights for material selection and structural design.
