When the axial force rose to a degree, the stress of contact area of workpiece achieved the yield strength of the material and the workpiece began to deform plastically.
The bandwidth is about 5kN and account for 4% when the material of the workpiece is 40Cr.
The better the plasticity of the workpiece material is, the bigger the fluctuation range of the axial riveting assembly force is.

Materials and methods Experimental animals and grouping. 20 adult male New Zealand rabbits were purchased from the experimental animal center of Xinjiang Medical University.
The form of damage is brittle fracture which is correspondent with the typical brittle material.
Therefore, when there is smaller load, the dense bone can be considered as linear elastic material
