Abstract
In this paper, the authors discuss rheological aspects of rheometers. The rheological classification of the dynamic behavior of materials is shown in Table 1. The features of the dynamic behaviors of non-thixotropic, nonlinear visco-elastomers are shown in Tables 2, 3, 4 and 5. The neccessary testing performances of rheometer for measuring the rheological properties of non-thixotropic, nonlinear visco-elastomers and of thixotropic materials are discussed.
