Paper Abstract

In this study a whole field, non-contact optical method, Stereo Digital Image Correlation (SDIC), was used to determine the strain distribution and mechanical properties of fresh bone in Phosphate Buffered Saline (PBS) solution. Knowing the whole-surface strain distribution of bone is useful for understanding the effects of normal physiological loading, disease, drugs and aging. In addition, knowing the mechanical properties of bone will aid in the design of new biomaterials. Although there currently are methods for measuring the mechanical properties of bone, these methods have some limitations. Many miss areas of strain concentration, especially because of the inhomogeneous nature of bone. SDIC overcomes these limitations by being able to precisely measure whole-surface 3D contour and strain of samples in solution over a wide range of deformations. In this study, SDIC was used to measure the axial strain of fresh chicken tibia. A setup which has the capability to apply force axially was designed. This paper describes the methodology of SDIC for measuring fresh bone in a PBS solution. The effect of drying time on strain distribution was investigated. The usefulness of the SDIC system is demonstrated by examples of deformation and strain measurements for different chicken tibia in PBS solution.
