Dynamic elongation of fluid and air filled elastic tubes: model for cerebral blood vessel trauma

A series of experiments involving dynamic elongation of both fluid- and air-filled elastic tubes has been conducted. This physical model allows closer study of the coupled fluid and solid mechanics problem associated with small cerebral blood vessels undergoing high-strain-rate loading as seen in traumatic head injuries. A small-scale materials testing device has been developed. The device consists of a solenoid driver, an isometric force transducer, an angular displacement transducer, and a fluid reservoir system. This device has been designed to produce high-strain-rate deformations in the specimens
