Strain associated with failure in tension for a porous rock
Abstract The Hoop Tension Test has proved to be a reliable and sensitive test for measuring rock strength in tension. This paper describes experiments using Penrith Sandstone hoops of different sizes, failed under tension by this procedure. The distribution and magnitude of strain over the surface of the hoops was measured using Moiré fringes, from which strains at failure were determined. The variation in strain at failure between the hoops of differing heights, failed at different rates of deformation, was determined. The strains appear to be dependent on total porosity but no single explanation accounts for the results obtained.
