Research Abstract

It is necessary to evaluate crack initiation and propagation after fracture because this process may be different in the case of injured bone tissues. In this study, we attempted to analyze the strain distribution on bone tissue surface by using image correlation techniques in order to elucidate the relationship between microscopic bone damage and strain distribution. A strain analysis performed using image correlation techniques allowed the visualization of the increased strain at the forward end of the slit of the specimens.
