Abstract
Negative pressures were produced in distilled water by reflecting 5 MPa−7 MPa shock pulses off a quasi‐free water‐Mylar‐air interface. An interferometer measured the displacement history of the interface. After the pulse’s trailing edge reaches the Mylar, the velocity does not tend toward zero as it would for an elastic solid. The velocity reduction or ‘‘pullback’’ was approximately 4 m/s. An approximation is derived which relates the pullback to the tensile strength. It appears that the Mylar separated from the water during pullback and the data places only a lower limit (2.8 MPa or 28 bars) on the tensile strength.
