ABSTRACT

In order to characterize TIH, we propose two criteria. Firstly, the test has to generate the three homogeneous loading conditions, namely UT, PS and ET. Secondly, for each loading condition, i.e. UT, PS and ET, a distribution of the maximal principal stretch ratio (defined as the ratio between actual and initial lengths) has to be observed and must be sufficiently large considering the chosen constitutive equations and its field of validity. In the following, these criteria are used to choose both sample geometry and loading conditions.
