Abstract

The understanding of the mechanical properties of bone is important to the understanding of bone repair. Previous studies have focused on macroscopic failure of bone material but have failed to provide evidence of strain evolution during mechanical testing. In this present study, we performed compression tests on lamb femurs to understand the failure mechanisms and the real time strain evolution in bones during compression testing. We examined the strain distribution patterns in specimen tested at three different strain rates and have also varied the specimen length to identify the effects of specimen length and strain rates during compression. The study has shown that the specimen lengths and loading rates have a significant effect on the failure behavior and strain distribution in bones.
