The present paper covers a failure criterion for heterogeneous layered media, based on the assumption that each of their components follows a Mohr-Coulomb type strength condition. The “homogenization technique” employed enables the formulation of a failure condition defined by four strength parameters; the procedure for the identifìcation of the parameters, starting from experimental data, is outlined. The model enables the description with fair accuracy of the ultimate behaviour of layered rocks submitted to triaxial tests, varying both the orientation of the principal stresses to the layers and the confining pressure.

Abstract
The present paper covers a failure criterion for heterogeneous layered media, based on the assumption that each of their components follows a Mohr-Coulomb type strength condition. The “homogenization technique” employed enables the formulation of a failure condition defined by four strength parameters; the procedure for the identifìcation of the parameters, starting from experimental data, is outlined. The model enables the description with fair accuracy of the ultimate behaviour of layered rocks submitted to triaxial tests, varying both the orientation of the principal stresses to the layers and the confining pressure.File in questo prodotto:
