Abstract
A novel device for measuring the viscoelastic properties of thickened liquids has been built and tested at DRES. The device involves the withdrawal of a thin metal rod from the liquid under test. The variation in force applied to the rod as the filament of liquid between the rod and the liquid surface relaxes and separates is monitored by strain gauges and displayed on an oscilloscope. The oscilloscope traces provide force time signatures unique to each combination of viscosity and elasticity, which can be photographed and compared. The apparatus and its development are described in detail and oscillographic signatures obtained from various viscoelastic liquids are shown. Some initial theory is discussed and some recommendations are set forth.
