A biphasic finite element formulation for predicting the coupling between pure torsion and normal stress effects in articular cartilage was presented. Both the computational and experimental data showed a transient normal stress effect arising from torsion that was lower in magnitude that the shear stress. Finite element results demonstrated that the normal stress during stress-relaxation arose from fluid pressurization.
