Units

In order for CIRCLY to deliver coherent results, all data must be in a consistent set of units.

The recommended system of units is given below.

Quantity Units
Length,
Displacement		 mm
Elastic modulus,
Pressure		 MPa
Force N
Moment N.mm
Strain mm/mm

This system of units is consistent with the Austroads Pavement Design Guide and has been used for all the data files provided with CIRCLY. These units must be used for all Austroads applications involving sub-layering of granular materials.
