One of the applications of Rocscience Phase 2 8.005 is to model country armadura emu (CAE), which is a type of reinforced soil system that consists of a geosynthetic reinforcement layer embedded in a compacted soil layer. CAE is used for various purposes, such as retaining walls, bridge abutments, embankments, and foundations.

In this article, we will show you how to use Rocscience Phase 2 8.005 to model CAE and analyze its performance under different loading and boundary conditions.

## Step 1: Define the Geometry and Mesh

The first step to model CAE with Rocscience Phase 2 8.005 is to define the geometry and mesh of the problem. You can use the built-in drawing tools or import a DXF file to create the geometry of the soil domain and the reinforcement layer. You can also specify the boundary conditions, such as fixed or free edges, supports, or loads.

After creating the geometry, you need to generate the mesh, which is the discretization of the domain into finite elements. You can use the automatic mesh generator or create a custom mesh with different element types and sizes. You can also refine the mesh in areas of interest or complexity.

## Step 2: Assign the Material Properties and Parameters

The next step to model CAE with Rocscience Phase 2 8.005 is to assign the material properties and parameters for the soil and the reinforcement layer. You can choose from various material models, such as linear elastic, Mohr-Coulomb, Hoek-Brown, Cam-Clay, or user-defined models. You can also define the material parameters, such as density, Young's modulus, Poisson's ratio, cohesion, friction angle, dilation angle, tensile strength, etc.

For CAE modeling, you need to assign different material properties and parameters for the soil and the reinforcement layer. For example, you can use a Mohr-Coulomb model for the soil and a linear elastic model for the reinforcement layer. You can also specify the interface properties between the soil and the reinforcement layer, such as bond strength and slip resistance.

## Step 3: Run the Analysis and View the Results

The final step to model CAE with Rocscience Phase 2 8.005 is to run the analysis and view the results. You can choose from various types of analysis, such as static analysis, dynamic analysis, transient analysis, or coupled analysis. You can also define the loading conditions, such as gravity load, surcharge load, seismic load, etc.

After running the analysis, you can view the results in various formats, such as contour plots, vector plots, graphs, tables, or reports. You can also export the results to other formats or programs for further processing or presentation. Some of the results that you can view for CAE modeling are:

Displacements: The displacements of the soil and the reinforcement layer due to loading and boundary conditions.

Stresses: The stresses in the soil and the reinforcement layer due to loading and boundary conditions.

Strains: The strains in the soil and the reinforcement layer due to loading and boundary conditions.

Forces: The forces in the reinforcement layer due to loading and boundary conditions.

Safety Factors: The safety factors against failure modes such as sliding or overturning.

These are some of the results that you can view for CAE modeling with Rocscience Phase 2 8.005. You can also perform sensitivity analysis or parametric studies to evaluate the effects of different variables on the performance of CAE.
