Hyperbolic Expression of Shear Stress-Strain curves Obtained by Burggra Shear Test

Abstract

There are three types of shear stress-strain curves as shown in figure 1. In this report, only the curve of type (2) was studied. The exponential expression (1) for curves of type (2) has been proposed by Janosi and Hanamoto for off-the-road locomotion. The author modified the hyperbolic expression proposed by Kondner used in triaxial tests of soil mechanics, applied it to express the curve of type (2) and examined which expression would give a better approximation with the result that the hyperbolic expression gave a closer approximation.
