N2  - The non-linear mechanical behavior of porcine brain tissue in different deformation modes is determined. An improved method for rotational shear experiments is used, producing an approximately homogeneous strain field and leading to an enhanced accuracy. Results from oscillatory experiments and constant strain rate experiments are presented. Large deformations at the time scale of loading and the material behavior during complex loading paths (loading-unloading) is investigated. No significant immediate mechanical damage is observed for these shear deformations. A new differential viscoelastic model is used to describe the non-linear mechanical response of brain tissue. This constitutive model is readily applicable in three-dimensional head models in order to predict the mechanical response of the intracranial contents due to an impact.<p />
