Measurement of Viscoelastic Properties of Some Recent Marine Sediments by a Torsionally Oscillating Cylinder Method.

Abstract

A torsionally oscillating cylindrical probe method, operating in the frequency range of 0.8 to 3.3 kHz was employed for measuring the viscoelastic properties of 13 marine samples collected by Shipek grab from shallow water regions of Monterey Bay, California. Other mass physical properties such as wet density, porosity, sound speed, sand-silt-clay-gravel percentages, mean grain size and sorting were also measured. Limited precision of impedance measurements permitted only the determination of the mechanical resistance due to the probe contact with the sediment. Correlations between mechanical resistance and mass physical properties are studied by graphical means with results indicating that water content of sediments is a determining factor in the mechanical resistance of a sediment. A dependence of mechanical resistance upon frequency is observed. (Modified author abstract)
