Question

I would like to define an orthotropic plate. In order to check the influence of the changed material properties on the stiffness matrix, I would like to know how the stiffness matrix is determined. Also, how is the self-weight of an orthotropic surface calculated?


Answer:

In RFEM, you can define various types of orthotropic surfaces. The information about the calculation of respective coefficients of the stiffness matrix is available in the "Stiffness Matrix" tab by clicking the [Info] button (see image).

The self-weight determination is based on the specific weight of the material as well as the values defined in the windows of the selected orthotropy type. To consider the self-weight, there are separate text boxes available where you can enter the equivalent plate thickness, for example.
