Interpretation of the false roots in the dispersion curves of thick plates
Hora, Petr ; Červená, Olga
This paper deals with the interpretation of the false roots appearing in the numerical computation of thick plate dispersion curves from isotropic or anisotropic materials. The examples of false roots, the reasons of their occurrence, the possibilities of their detection and removing are presented here. Dispersion curves are computed for steel and the unidirectional composite.
Vyšetrovani elastickych vlastnosti hovězi kosti ze vzorku obecného tvaru
Goldmann, T. ; Seiner, Hanuš ; Landa, Michal
This work contributes to the methodology of an evaluation of elastic properties of cortical bones by ultrasonic wave inversion, whilst the bone is considered to be a linear elastic anisotropic continuum.
