Abstract
Bone plates are often applied on the treatment of long bones diaphyseal fractures and, for that, high mechanical, fatigue and corrosion resistances are expected; so, it is very important to have a reliable projection of its mechanical and biological behaviour. In this work, some available AISI 316L and Ti-6Al-4V ELI straight bone plates were picked and submitted to static and fatigue bending tests according to ASTM F382 standard, in order to be compared. After that, using computer modelling and numerical simulation, stress states acting over an implanted bone plate were calculated. The main conclusion of this work is that tests according to ASTM F382 present important evaluation of bone plates, but a critical analysis of the results based on finite element method is essential to diagnose if they are adequate to the biomechanical scenario to which they are exposed.
