How can I save frequently used membrane materials in RFEM?


For lightweight structures, there are many technical membranes.

  • Polyester fabric (PES) coated with polyvinyl chloride (PVC) → PES/PVC
  • Polyester coating covered with Polyvinyl Chloride (PVC)
  • Glass fabric → Glass/PTFE, coated with polytetrafluoroethylene (PTFE)
  • Polyester Fabric (PES) coated with Polyolefin
  • Polyester fabric (PES) coated with fluoroplastic 
  • Glass fabric coated with silicone
  • Open and closed mesh fabrics
  • Uncoated and natural fabrics
  • Ethylene-tetrafluoroethylene foils → ETFE
Depending on the various properties, RFEM selects these materials for the respective project for each structural task. With regard to the structural analysis, all products have different load-bearing properties, some of which can vary with each production batch.

In RFEM, you have to enter these different values in material table 1.3 in connection with an appropriate material model.

There are model templates for the recurring use of materials in different models. Any selected list of membrane materials can be stored and loaded directly when opening a new model. 

In most cases, membrane materials always consist of an interaction of solid material values and a material law. Since the existing material library only organizes materials with the material law “Isotropic Linear Elastic”, this database is not applicable for orthotropic membrane materials.
