- One Concern With Metallic Implant Materials Gold For Example 82gpa Is That Their Density And Modulus Of Elasticity Dwa 1 (27.54 KiB) Viewed 36 times
One concern with metallic implant materials (gold for example=82GPa) is that their density and modulus of elasticity dwarf those of the bone they replace. One option is to consider whether porous metallic foams could satisfy the same requirement more effectively. Using a simple rule of mixtures model where the volume fractions of each component (air and gold, for example) combine to form a composite property: Question 25 5 Points Calculate what level of porosity is needed to match the modulus of the surrounding cortical bone. Add your answer 5 Points Question 26 What is the corresponding volume fraction of the gold. Add your answer
