Abstract
Methods and systems for measurement of mechanical properties of elastomeric materials use a driving point impedance head such as a load cell instrumented hammer to apply forces to a force distribution mass positioned over a test specimen upon a rigid base. Broad frequency responses of the driving point impedance head reveal elastic and viscous moduli response frequencies from 0 Hz to 2000 Hz. Methods and systems for measuring responses of elastomeric materials under a preload are also disclosed.
