000022752 520__ $$2eng$$aIdentification of mechanical properties of anatomical elements is crucial in the process of creating numerical models. The modelling process relies on the knowledge of modelled elements material properties. Bones are inhomogeneous and anisotropic, but in the numerical simulations the bone material is simplified to the elastic isotropic martial therefore it is necessary to determinate the Young's modulus and Poisson's ratio of bone. There are few main experimental tests to determine Young's modulus, such as static tensile or compressing probe, three or four-point bending. To calculate the Poisson's ratio the extensometer can be used however it should be noticed that this method is burdened with many errors due to the incorrect fixing of the sensor. In this paper authors present new approach to identification of anatomical elements mechanical properties. The described method includes three point bending to determinate the Young's modulus with simultaneous digital image correlation (DIC) to determinate the Poisson's ratio. The obtained results indicate that with the use of DIC technique the Poisson's ratio and also the Young's modulus can be calculated with higher accuracy.
