Mechanical properties of biomaterials

The mechanical properties of a biomaterial can best be described by its modulus of elasticity, ultimate tensile strength, elongation to failure, and fracture toughness.  Modulus of elasticity describes the stiffness of the material and is usually obtained from the slope of a stress  Ultimate tensile strength describes the ability of the material to withstand a load before it fails.  Elongation to failure desc before it fails.  Fracture toughness is an important measurement of the material's resistance to crack propagation.
