Are different stiffnesses possible for the x and y directions of a surface in RFEM?


Yes, it does. For this reason, orthotropic properties can be defined either for the material or for the surface.

Orthotropic material:

Enter the elastic moduli of the material for the two surface directions (if the additional module RF-MAT NL is not licensed, only the material models 'Isotropic Linear Elastic' and 'Orthotropic Elastic 2D/3D' can be used). Then, assign the material to the surface.

Orthotropic surface:

Define the stiffness type of the surface as 'Orthotropic.' Then, you can define the coefficients of the local stiffness matrix according to different criteria.
