Area of Science:

  • Biomechanics
  • Materials Science
  • Thermography

Background:

  • Elastic materials exhibit temperature changes with volumetric variations under adiabatic conditions.
  • Thermographic stress analysis (TSA) leverages this principle by measuring surface heat flux to infer surface temperature changes related to stress and strain.
  • This thermoelastic effect forms the basis for non-contact stress and strain analysis.

Purpose of the Study:

  • To investigate the feasibility of applying thermographic stress analysis (TSA) for biomechanical assessments.
  • To correlate thermographically measured heat flux with strain gage data in cortical bone specimens.
  • To establish TSA as a viable technique for experimental stress analysis in bone.

Main Methods:

  • Rectangular specimens of bovine femoral cortical bone were prepared.
  • Specimens were subjected to sinusoidal loading at a frequency of 20 Hz.
  • Heat flux was measured using thermography, and results were compared with strain gage data.

Main Results:

  • A significant linear correlation was observed between TSA measurements and mechanical parameters.
  • These parameters included stress, strain, first strain invariant, and strain energy density.
  • The loading frequency allowed for accurate measurement of thermoelastic-induced temperature changes before significant attenuation.

Conclusions:

  • Thermographic stress analysis (TSA) is a promising technology for experimental stress analysis in cortical bone.
  • The technique effectively relates measurable heat flux to mechanical stress and strain.
  • TSA offers a non-destructive and potentially more comprehensive method for evaluating bone biomechanics.
