The Methodology of Measurement of Biomechanical Properties of Biological Materials

Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of biophysics and physical chemistry Candidate: Mgr. Monika Kuchařová Supervisor: Prof. Ing. RNDr. Stanislav Ďoubal, CSc. Title of Doctoral Thesis: The methodology of measurement of biomechanical properties of biological materials As a part of this dissertation thesis a methodology of measurement of mechanical properties of viscoelastic materials was developed. The methodology was then verified and applied in measurement of shoulder-blades of pheasants and in measurement of the trabecular section of human caput femoris in bending and twisting stress, viscoelastic parameters of these materials were also calculated. Results, in the case of human bones, were compared with measurement of body mass density and content of vitamin D. Mechanical behaviour of many biological materials corresponds to the behaviour of so- called viscoelastic body. These materials cannot be categorized simply as solids or liquids. The mechanical behaviour of this type of materials has partially elastic and partially viscose character. Skin, cell walls, bones, numerous structures of internal organs and many other materials belong to this category. In spite of the fact that in physiological conditions biological materials are loaded dynamically, in..
