Shell

In RFEM, there are the following possibilities for modeling, for example:

  • Quadrangle surface
  • Rotated surface
  • Pipe
  • B-spline surface
  • NURBS surface
  • Trajectory surface

Shells are stressed by bending and membrane forces. If the thickness of a shell is small in comparison with its span, the load is usually transferred by membrane forces.

As described in FAQ 002727, the modeling using quadrangle surfaces is preferred in the case of complex models.
