Abstract: A dynamic mechanical analysis system provides an actuator that imparts expansion and contraction forces (e.g. shear force) to a viscoelastic material at high frequencies. Such high frequency analysis allows for the direct and accurate measurement of the characteristics of the material at high expansion/contraction frequencies directly, without the use of additional predictive analysis techniques, such as time-temperature superposition.

As such, the system is able to subject the viscoelastic material sample to simulated “road” conditions to identify various performance properties associated with the material sample.
