WebFor every test, the horizontal shear stress is plotted versus the shear displacement. Depending on the soil density, a different behavior in terms of shear strength-shear strain is presented. Dense sand or over-consolidated clay samples tend to obtain a maximum shear stress that subsequently drops reaching a fixed value known as residual strength.
