Abstract
A high strain rate tester for elastomeric materials used in sports balls includes a base on which a sample of the material is mounted and a striker which delivers an impact to the sample, preferably in the vertical direction. A load cell adjacent to the sample measures the reaction force of the impact from the sample and an optical detector measures the displacement of the sample in the vertical direction. The force and displacement measurements are processed to determine the time dependent strain of the material.
