2-dimensional cross sections of structural profiles.
StructureProfile type, containing data of a structure profile cross sections. The cross section profile is defined by several points (->pointList) in the x-y-space. Two points are combined to one sheet (->sheetList) by using the pointUIDs.
This profile is defined by several points in the x-y-space. Allways two points are combined to one sheet. The properties of each sheet are defined in the 'sheetProperties' section by referencing on the sheetUID and the material properties. The orthotropy direction of composite materials equals the x-sheet axis. The orthotropy direction angle equals a positive rotation around the z-sheet axis as indicated in the picture below (part 3.), where a wing stringer is defined as an example:
