Calculation RFEM 5.xx

When analyzing an orthotropic surface (for example timber plate), an error message appears saying that the Poisson's ratio has to be within a certain interval. What should I do?


In this case, it is not sufficient to only set the stiffness type to "orthotropic". It is also necessary to select an orthotropic material model for the material, otherwise the stiffness material is defined singularly.

Key words

stiffness type, orthotropic
