ABSTRACT

Unlike industrial materials, biomaterials are very complicated. Building an accurate finite element model that is close to the true biology should take many factors into account. For example, relative stiffness must be considered. One material may be modeled differently depending on its stiffness relative to that of connected materials. The time factor also makes a difference. To study instant mechanical behavior, soft tissues can be regarded as elastic. On the other hand, the soft tissues should be modeled as porous media in its creep study. Macroscale/microscale is a reminder that bone has different material properties.

Finally, different contact behaviors correspond to different contact key options. This chapter also discusses mesh sensitivity, units, workbench, and ANSYS versions.
