Strain rate effects on tensile failure properties of the common carotid artery and jugular veins of ferrets.
We have recently reported the insensitivity of tensile failure properties of human cerebral bridging veins to strain rate. Due to data scattering, however, concerns remain regarding this finding. To pursue the issue further, the common carotid arteries and external and internal jugular veins from seven ferrets were stretched longitudinally in vitro at either a low strain rate of 0.2-2.0 s-1 or a high rate of approximately 200 s-1. The ultimate stretch ratios and loads were found to be independent of strain rate in all the vessels tested. Therefore, the present results appear to support our previous finding on human bridging veins.
