A composition describes the type, properties, and position of the individual layers across the thickness of a multilayer flat structural component.
Similarly to a cross-section of a beam component, the composition can be seen as a cross-section of a surface component. By optimally determining the layer type and position, certain global properties of the composite surface can be improved compared to a similar single-layer, homogeneous surface with regard to its area of application. In the area of structural engineering, the multilayer components are thus used in many places.
Examples of Layer Structures
- Sandwich panel consisting of a foam-like insulation core and two outer metal cover plates
- Cross-laminated timber panel made from several board layers laid flat on top of each other crosswise
- Insulated glass pane consisting of at least two glass panes with a gas layer between them
Implementation in RFEM
Using the Multilayer Surfaces add-on, you can generate laminate surfaces, such as cross-laminated timber, according to the laminate theory. The Glass Design add-on allows you to design laminated glass panes (insulated glass panes are in preparation).
