Development of a Finite Element Digital Human Hand Model

The aim of this research was to develop an anatomically accurate and numerically feasible and stable finite element digital human hand model, which would allow accurate bio-mechanical behavior during movement and grasping. Therefore, correct anatomical geometry of the hand has been defined based on CT images, which has been then used for the definition of the finite element model. Using the finite element software, material properties and boundary conditions have been defined to obtain accurate movement of the bones and deformation of the skin. The result of the conducted research is a developed angle-driven finite element digital human hand model, which is numerically stable. Using the accurate geometry and correct definition of the material properties and boundary conditions, the finite element digital human hand model shows reasonable bio-mechanical behavior under movement.
