Slide 8

The torsional stiffness is found in the same manner as for the engineered materials. The torque-twist curve is plotted over a small range. The linear portion of the data is extracted, and a straight line is fit to this data. The slope of the line gives the torsional stiffness. Note that in contrast to the tests of aluminum and iron, the stiffness of the bone is so low relative to the test machine stiffness that correction for finite test machine stiffness is not needed.
