Abstract

The purpose of this paper was modeling and mechanical analysis of the biodegradable biphasic calcium phosphate/silk (BCP/Silk) laminated composite bone plate for fractured tibia healing; to this aim,ABAQUS 6.13 was employed for modeling and mechanical analysis. First, the tibia bone was considered based on the anthropometric measurements of an average person as a two-layer cylinder; the inner part was the bone marrow and the outer one was the cortical bone. Then, the bone plate and screws were designed according to the defined standards and the properties of new composite in the ABAQUS software. The mesh of bone plate and other equipments were selected to be tetragonal and cubic, respectivelly. After that, the bone plate was placed on the bone while the bone was bounded along the Y axis and the force of around 400 N was loaded. The results showed that the biocompatible and biodegradable composite bone plate had the elastic modulus of about 21 GPa, which was close to the bone modulus.
