Determination of Elastic Coefficients of Bone and Composite Materials by Acoustic Immersion Technique

Popis výsledku v původním jazyce

This paper contributes to methodology of evaluation of elastic properties of bones by ultrasonic wave inversion. The method was developed on composite structures like as plates and cylindrical shells. The final results are then demonstrated on the bovinecortical bone specimen. The properties are supposed to exhibit orthotropic or transversally isotropic symmetry. The quasi-longitudinal and quasi-transverse waves are generated from wave diffraction on liquid/specimen interface. The wave velocity fieldsobtained by the ultrasonic scanning technique are used as an input to inversion procedure for all elastic constants determination. The stability of resulting data is evaluated by the statistical method based on Monte-Carlo simulation. The suggested approach has a potential for qualify of such measurements performed on fresh bones and also for improvement in-situ ultrasonic techniques.
