Paper Abstract

Biomechanics place huge challenges on existing measurement technologies for determining the mechanical properties of these materials, as well as just measuring the full-field displacement and strain of these materials. 3D Image Correlation Photogrammetry is proving to be a powerful tool for these measurements, providing full-field 3D measurement of the specimens under normal loadings, even at high-speed. This optical technique is independent of the material that it is measuring, providing a non-contact measurement of any material or geometry type. The results are then directly comparable to finite element models for model verification, iteration and boundary condition determination. This paper discusses the theory of the technology, and its application in deformation and strain measurement of real biomechanic applications, from tissues and organs to ligaments and bones.
