Constitutive Modeling is the mathematical description of how materials respond to various loadings.
The Center for Applied Biomechanics is focusing on constitutive modeling of biological material in order:
  • To aquire a better knowledge of the response of biological materials under high strain rate loadings (specific to car crash rates)
  • To Obtain material properties that can be integrated in finite element human body models.

Constitutive models were developed for numerous biological materials:
A finite element optimization approach has also been exploited [Untaroiu06, Lee07] to obtain optimal sets of constitutive parameters.

Some of our capabilities to load the biological samples and investigate the constitutive parameters include:
  • an indentation instrument
  • electromagnetic shakers for creating biaxial deformation
  • Instron Material Test System
  • viscoelastic Hopkinson pressure bar [Cheng98]
