Abstract:

A proposed technique for describing the stress-strain relations from triaxial tests and pressure-sinkage relations from plate-penetration tests on sand and clay specimens prepared in the laboratory was studied. This technique, which is based on the characteristics of a rectangular hyperbola, was found to portray adequately the stress-strain relations examined. The pressure-sinkage relations usually require one hyperbola to describe the relation at shallow sinkages and another for greater sinkages. Certain of the hyperbolic parameters were found to be related to the physical characteristics of the soil test specimens. It is recommended that the study be extended to a wider range of soils and test conditions. Author
