Anisotropic Strength

The Anisotropic Strength model allows you to define Anisotropic strength properties for a soil or rock mass, by defining cohesion and friction angle in two orthogonal planes.

Required parameters are:

  • Cohesion 1 and Phi 1 - cohesion and friction angle in the plane defined by the dip and dip direction of Plane 1
  • Cohesion 2 and Phi 2 - cohesion and friction angle in any plane perpendicular to Plane 1
  • Dip of Plane 1 / Dip Direction of Plane 1 - this defines the orientation of a plane in 3 dimensions, in which the strength parameters cohesion 1 and phi 1 are applicable. Typically this will be a plane of weakness.

NOTE: Dip Direction of Plane 1 is the azimuth of the plane with respect to north (north = zero degrees). In a Slide3 model, the y-axis is always the north direction. Therefore you must define the dip direction accordingly.

The cohesion and friction angle for any arbitrary plane is then given by:

Cohesion and Friction Angle Equations

where alpha ( a ) = the minimum (acute) 3-dimensional angle between Plane 1 and the shear plane (e.g. column base plane).

The Anisotropic Strength model in Slide3 could also be referred to as Transversely Isotropic Strength.

Tensile Strength

See the Tensile Strength topic.

Generalized Anisotropic Strength

A more general anisotropic strength criterion can be defined with the Generalized Anisotropic failure criterion option.
