Some failure conditions for heterogeneous layered media, formed by two alternating homogeneous materials, are presented. The failure criteria have been obtained by a homogenization procedure, on the basis of the criteria of the materials forming the layered medium. The paper deals with layers formed by Mohr-Coulomb’s type materials (the cases of cohesionless materials or materials provided by the same friction angle are discussed), as well as with layers undergoing the maximum tensile stress criterion. Theoretical predictions are in good agreement with the experimental results obtained by other authors on layered sands and laminated rocks.

Abstract
Some failure conditions for heterogeneous layered media, formed by two alternating homogeneous materials, are presented. The failure criteria have been obtained by a homogenization procedure, on the basis of the criteria of the materials forming the layered medium. The paper deals with layers formed by Mohr-Coulomb’s type materials (the cases of cohesionless materials or materials provided by the same friction angle are discussed), as well as with layers undergoing the maximum tensile stress criterion. Theoretical predictions are in good agreement with the experimental results obtained by other authors on layered sands and laminated rocks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
