| Abstract: | Objective To make the research on the biomechanical properties and viscoelasticity with fresh adult corpse to provide the biomechanics parameters for clinic. Method The stress relaxation and creep tests were made. Result The reduced stress relaxation function and creep function were obtained by making the experimental data normalization and then using regression analysis to obtaine the coefficient and fitting curve. Conclusion The quantities of stress relaxation and creep of MCL are lower than that of ACL in 7200s. The experimental results were analyzed and discussed. |
