title: Single versus double ended high frequency pressurization of mock arteries: symmetry of expansion.
abstract: A series of experiments was carried out to evaluate the expansion characteristics of silicone mock arteries at frequencies from 5 to 100 Hz. Of particular interest was the magnitude of expansion along the length of the tube versus frequency. The tubes were pressurized from one end or from both ends. In general, results indicate asymmetric expansion along the length of the tube. This asymmetry, however, changed dramatically with frequency. These changes are not fully explainable by standard experimental considerations such as compliance and harmonics.
