Cartilage is a complex tissue,
capable of withstanding large compressive loads during everyday activities.
Determining the mechanical properties of articular cartilage is important for
understanding how the tissue behaves in vivo, how the tissue properties
might change with age, injury, or disease, and also how we might try to replicate
the function of cartilage using tissue engineered constructs. Many researchers
have investigated ways in which to test the material properties of cartilage
and described cartilage using different material models. The purpose of this
research is to develop a robust and computationally-efficient method to calculate
cartilage material properties using creep or stress-relaxation indentation experiements.
