Shock-like waves are generated in fluid-filled silastic tubes, and their amplitudes recorded as a function of position and time. A simple theory is formulated for the steady-state “shock-structure”, based on a mathematical analogy with gas-dynamic shock waves. Comparison with the experimental results provides a general method for the evaluation of the dynamic rheology of viscoelastic biological vessels. The existence of shock-like propagation is seen to depend upon the form of the input pressure signal and most critically upon its maximum rate of rise dp/dt.
