Closure

Test results from the use of the Geonor direct simple shear (DSS) device to measure nonuniform stress-strain behavior on specimens of elastic rubber and actual soils are merely corroborative and allow conclusions to be made about the device. Tests on rubber specimens do not represent soil behavior but contribute in understanding the pronounced strain softening always observed at large shear strains during K(sub O) consolidated-undrained DSS tests on cohesive soils.
