Mechanical properties of bone in compression

The objective of this project is to evaluate the difference in mechanical properties of the porcine femur and humerus bones using compression testing. Cylindrical samples were cored from slabs of porcine femur and humerus bone using a diamond coring tool. Compression tests were performed using a str...
