Material

Select the material of the 3D object in this list. The equivalent material properties are calculated according to EN 13947, depending on the diameter and the distance.

The standard EN 13947 assumes that the material  between the 3D objects has a negligible smaller conductance than the material of the 3D objects. Therefore the influence of this material is not considered in the formula for calculating the equivalent conductivity of the screw.

If you decide to consider the material in the background (e.g. for simulating armoring irons as equivalent 3-dimensional object) you have to check the Consider materials in the background option.

Type

Here you define the type of the periodically appearing 3D object. Following types are supported:

Screw: periodically appearing screws. The screw head and screw pile shaft have the same material properties.

Rectangular cross section: periodically appearing disturbances with a rectangular cross section.

Consider materials in the background

Is this option checked, then the material in the background is considered too. The equivalent conductivity is calculated as area weighted average of both materials  (3D object and background).

Diameter respectively depth

Diameter of the screw pile shaft respectively depth of the rectangular cross section

Distance

Axis distance of the periodic 3D objects
