How Does Bone Detect Cracks?
We conducted work to investigate fatigue cracking and repair in bone, in which we discovered the mechanism by which bone is able to detect the presence of microscopic cracks and thus initiate repair processes. This investigation has made use of theoretical and applied fracture mechanics, in combination with cell biology. It is the first example of a completely-understood mechanism showing how living cells can respond to mechanical stimuli.
