Three-dimensional modeling and analysis of a human ankle joint
Developing an accurate finite element model of an ankle joint is a challenging task and time consuming. Several steps were utilized to minimize over-simplification of the model as can be found in literature. The objective of this study is to biomechanically analyzed, via the finite element method, a...
