This example provides a basic introduction to the SR4 elastoplastic material model for weakly cemented rock.  An overview of the model theory and a discussion of its application are provided and a set of single element triaxial test simulations are used to demonstrate the characteristic response obtained using the model.   Specific issues considered are:

 

1Model theory and applicability to weakly cemented rock.

2Creating a material characterisation using experimental triaxial tests

 

The example documentation assumes that the user is familiar with mesh generation and single field geomechanical modelling functionality and the following examples should undertaken beforehand:

 

1Mech_001 Mechanical Analysis Introduction

2HM_001 Introduction to Hydro-Mechanical Analysis - Uniaxial Consolidation

 

Overview of SR4 Model

 

Case 1 Simulation of Triaxial Tests with the SR4 Model

 

Case 2 Characterisation of Experimental Data with the SR4 Model (linear elasticity)

 

Case 3 Characterisation of Experimental Data with the SR4 Model (poroelasticity)
