1. A bioengineering textbook reports the Young’s modulus and shear modulus of cortical bone to be 18 GPa and 6 GPa, respectively. What do these material constants represent, and how are they different from one another? 2.The figure below shows stress-strain curves for both wet and dry human femoral bones loaded to failure. Which material is more brittle? How can you tell? (Note that the units of stress are given as 103 lb/in2.)
