Material Properties Overview
Material properties in RS2 are the physical and hydraulic properties of the rock or soil which make up your model. There are two basic steps required to specify the material properties for your model:
- Defining material properties
- Assigning the properties to the various regions of the model
These options are summarized below.
Define Material Properties
Material physical properties such as unit weight, strength and elastic parameters, are entered in the Define Material Properties dialog.
Note: Properties can also be imported from other RS2 files, using the Import Properties option.
Define Hydraulic Properties
If your model considers groundwater pore pressure (e.g. for effective stress analysis) or flow, then the hydraulic properties of each material (e.g. piezometric surfaces or hydraulic conductivity) are entered in the Define Hydraulic Properties dialog.
Define Thermal Properties
If your model includes a Thermal Analysis, (the Thermal Analysis option is enabled in Project Settings), then the thermal properties of each material can be defined in the Define Thermal Properties dialog. Depending on the selected thermal method, the available options in the dialog will be different.
Stage Factors
In RS2, the material properties can vary by a factor with stages. This can be done by assigning a stage factor to the property. The feature is under the Stage Factors tab in the Define Material Properties dialog, with three categories of properties:
- Stage Strength/Stiffness Properties
- Stage Hydraulic Properties
- Stage Thermal Properties – Thermal Grid to Use (only available for Static Temperature method of thermal analysis)
Assign Properties
Material properties and the excavation staging sequence are assigned to the various regions of your model using the Assign Properties option.
