| Abstract: | To study the viscoelastic properties of L4 lumbars got from fresh corpse of our country to provide parameter of biomechanics for clinic.The test of stress relaxation and the creep on them with Shimadzu AUTOGRAPH electronic universal testing machine were done.The data and curves of stress relaxation and creep were got.The data were dealed with three parameter model and the function of stress relaxation and creep were got.It proves that the L4 spine's stress relaxation quantity is 0.232MPa and the creep quantity is 0.271% |
| Keywords: | Spine Lumbar Cancellous bones Function of stress relaxation and creep |
