Answer to Question #111663 in Mechanical Engineering for viviannouy

Question

Predict the number of loading cycles to failure for cortical bone loaded to 2500 us in compression. Explain how bone remodeling can affect fatigue life

Answer 1

As the fatigue is tested under normal condition of loading and at normal temperature, for the range of 2500 in compression loading we have

Number of cycle=$2500^{0.6}\times 10^6 cycles$

Number of cycles= $1.09\times10^8 cycles$

As we know that the life time dissipation energy is fitted with the same power law from that we are getting the compression range to 4500 and thus in this way phenomena play a role in initiating the remodeling response in live bone tissue.
