This project involves ultrasonic characterization of fatigue damage accumulation in cortical bone. Most fatigue testing done so far has been destructive in nature and has measured fatigue failure mechanism only in the direction of loading. Since ultrasonic measurements can be made in many directions for each specimen, it has a great advantage over traditional fatigue testing procedures in characterizing the microstructural response in bone.
Ultrasound technique provides better insight into the fatigue failure mechanism.
This project will seek to determine how these measurements depend on factors related to the mechanical integrity of bone. Back to Project Titles .
