Monitoring of trabecular bone induced microdamage using a nonlinear wave-coupling technique

Trabecular bone tissue contains microcracks which may affect its mechanical properties as well as the whole structure. A Dynamic AcoutoElastic (DAE) method based on two acoustic waves coupling was developed to measure viscoelastic and dissipative nonlinearities in trabecular bone. The purpose of thi...

Zusammenfassung:Trabecular bone tissue contains microcracks which may affect its mechanical properties as well as the whole structure. A Dynamic AcoutoElastic (DAE) method based on two acoustic waves coupling was developed to measure viscoelastic and dissipative nonlinearities in trabecular bone. The purpose of this work is to validate the technique sensitivity to monitor microdamage in human calcaneus.
