Deformation of Isodamp (A Polyvinyl Chloride-Based Elastomer) at Various Loading Rates.

摘要

Elastomers are widely used for mitigating and blocking small amplitude and low frequency vibrations. There is an interest in utilizing this material in dynamic loading environments where it would be subjected to high strain rates and high pressures. Since a paucity of information about elastomers exists in this environment a study was initiated. The objective of the study was to determine how the shock absorbing property of Isodamp C-1002 is modified under high strain rates of deformation and high stresses. In this investigation measurements of elastic wave velocity and attenuation to 10 MHz were obtained using ultrasonic techniques.
