Abstract

The method of double-exposure holographic interferometry was applied to study the mechanical behaviour of an embalmed human tibia under simultaneous torsion and bending loading. The tibia was considered as a cantilever beam fixed at the knee and loaded at the ankle. The deflections were calculated from obtained holographic interferogram. The simultaneous bending and torsion make it easy to obtain the information about derivative values of deflection functions. The bone rigidity was calculated from differential equation of beam being bent as the product of Young's modulus E and cross-sectional moment of inertia I along the long axis. The advantages of the holographic technique in biomechanical research were pointed out.
