General principles of bone tissue testing

Five basic principles that govern the structure and biomechanical behaviour of biological tissue have been analysed. Many different factors of the mechanical and biological origin, which can significantly affect the mechanical properties and, consequently, the mechanical behaviour of the bone tissue are presented and discussed. The effect of structural levels in the bone tissue on the selection of proper size of the test specimens is emphasised. Different aspects of the testing procedure of bone tissue are discussed. Peculiarities of the distribution of its biomechanical properties in the man left tibia are described.
