Název v původním jazyce

Propagation of Acoustic Waves in Composite Materials and Cortical Bone

Popis výsledku v původním jazyce

This work contributes to the methodology of an evaluation of elastic properties of cortical bo- nes by ultrasonic wave inversion, whilst the bone is considered to be a linear elastic anisotropic continuum. Velocities of acoustic waves are used as an input data into inverse problem and they are experimentally detected by means of the ultrasonic based pulse-echo immersion technique. This method was developed on composite structures such as plates and cylindrical shells. The geometry of bone specimens is also implicated into algorithm by the model of wave propagation through curvilinear anisotropic sample based on the simplified ray method. The stability of re- sulting data is evaluated by the statistical method based on the Monte-Carlo simulation. Two additional ultrasonic based experimental techniques, the pulse through transmission contact me- thod and the resonant ultrasound spectroscopy (RUS), are tested here in order to validate and improve a wave inversion access.
