A layer structure describes the type, properties, and position of the individual layers over the thickness of a multi-layer planar component.
Analogous to the cross-section of a beam component, the layer structure can be seen as the cross-section of a planar component. With an optimal definition of the type and position of the layer, certain global properties of the composite surface can be improved compared to a comparable single-layer, homogeneous surface in terms of its field of application. Therefore, multi-layer components are used in many areas of construction technology.
Examples of layer structures
- Sandwich panel consisting of a foam-like insulation core and two outer metallic face sheets
- Cross-laminated timber panel composed of multiple crosswise flat stacked board layers
- Insulating glass pane consisting of at least two glass panes with an enclosed gas layer
Implementation in RFEM
With the Multi-layer Surfaces add-on, laminate surfaces like cross-laminated timber can be analyzed according to laminate theory. The Glass Design add-on enables the design of laminated glass panes (insulating glass panes are in preparation).
