SlopeSR Plugin for Abaqus

SlopeSR Plugin for Abaqus

The SlopeSR Plugin used the strength reduction method (SRM) to find the factor of safety (FoS) of a slope using the finite element method (FEM). The FoS of a slope can be defined as the factor by which the original shear strength parameters must be discounted to bring the slope to the critical equilibrium state, i.e., the verge of failure. When the strength reduction technique is used to calculate the FOS, it is usually necessary to solve a series of elastic-perfectly plastic problems with the strength parameters and in the Mohr-Coulomb criterion. The plugin is used to solve it in ABAQUS/CAE.

Features/Technology

• Obtain safety factors and critical slip surfaces for 2D & 3D slopes.
• Slope stability analysis in geomechanics and geotechnical engineering.

Workshops/Examples

• Example 1: a 2D geometrical model of homogeneous slope
• Example 2: a 3D geometrical model of homogeneous slope

Installing the Plugin

Extract the contents of the zip folder into a subdirectory of the abaqus_plugins folder, which can either be located in the

• abaqus_dir\code\python\lib\abaqus_plugins where abaqus_dir is the Abaqus parent directory or,
• home directory (in which case the plugin will be available whenever Abaqus is run) or,
• within the current working directory of your Abaqus/CAE session.

Compatibility

The Plugin is designed to be compatible with Abaqus/CAE 6.14 and later.

Updates
