    Kryterium wytrzymałości geomateriałów z mikrostrukturą warstwową
    (2008) Kawa, Marek; Łydżba, Dariusz
    The paper presents anisotropic failure criterion of geomaterials with microstructure of layered type. The microstructure is considered as composed of two constituents periodically distributed in the space. Both constituents are assumed to be isotropic with strength ruled by Druckcr-Prager criterion. The overall strength condition proposed is a conjunction of Pariseau anisotropic failure criterion and critical plane equation. Usefulness of this description is verified based on the homogenization theory procedure. Material constants are defined, in an analytical form, as a function of strength parameters of the constituents. As an example of criterion application the results of load carrying capacity of layered soil are presented for different orientations of layers. The results clearly show influence of strength anisotropy of material on the solution of boundary-value problem.
