Abstract

In this paper a constitutive equation is proposed, which is derived on the basis of experimental results of simple shear tests. In the constitutive equation shear modulus decreases with increase of maximum shear strain, while Young’s modulus is kept constant, so that the material damages caused by shear strain can be taken into account. In order to demonstrate the applicability of the constitutive equation to engineering practices both tunnel and land-slide problems are solved.
