Constitutive Modeling Print
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]
