Abstract
The formulation of the relationship among the external applied force, internal stress and strain of bio-material is difficult due to its non-linear properties. Thus for simplification, bio-material relaxation and creep under certain load are mainly discussed under step stress and strain functions. The goal of this study is to show the influence of the external force loading rate on the maximum magnitude of the internal stress or strain. The change of the stress and strain is studied based on the assumption that the volume of the material remains unchanged. The results are used to explain the failure of bio-materials happens at different tensile load under different loading rate. The problem is analyzed and verified using both computer and experimental results. This study provides the basis for the description of the dynamic properties of biomaterials.
