Abstract:
This paper presents key results of studies in applications of MATLAB tools in experimental data analysis and curve fitting method of the modal analysis to determine mechanical properties of human bones in vivo from frequency response data. In studies and analyses, a seven parameter model of a bone from the mechanical response tissue analyzer (MRTA) method, offering an approach to separate the effects of the soft tissue and bone, is employed within the frequency range of 400-6000 . The study results showed adequacy and appropriateness of applying MATLAB tools for curve fitting and determining mechanical properties of human bones in-vivo studies based on measured data of complex number valued frequency response functions and fitted data with a coefficient of determination of R2 = 0.956 â€¦0.988.
