Current computer studies utilize linear material properties when
modeling human ligaments.
This study demonstrates the need for nonlinear
property analysis, and the feasibility of such an approach to model the
scapholunate ligament of the human wrist in three dimensions.
To date, computer simulations of human joints have utilized linear
mechanical properties to model ligament behavior.
These models include both
finite element analyses and rigid body dynamic models.
The linear mechanical
properties have been based either on the ligament ultimate strength, or the
upper quasilinear portion of the force - elongation curve.
To model ligament material properties, mechanical testing to failure has
been made of...
