Answer to Problem 32AAP
The stress at the fracture site if the implant material is made of titanium and stainless steel is
Explanation of Solution
Express the relation for isostrain model.
Here, strain in the bone and implant material is
Express the load over bone if the implant material.
Conclusion:
Express the compressive load applied to the bone implant system.
For titanium implant material:
Substitute
Substitute
Hence, the stress at the fracture site, if the implant material is made of titanium, is
For stainless steel implant material:
Substitute
Substitute
Hence, the stress at the fracture site, if the implant material is made of stainless steel, is
