计算 RFEM

I want to define an orthotropic plate.

To check the influence of the changed material properties on the stiffness matrix, I would like to know how the fields of the stiffness matrix are calculated.

And how is the self-weight calculated for an orthotropic surface?

回答

In RFEM, you can define many different types of orthotropic surfaces. The respective calculations of the coefficients of the stiffness matrix can be shown by using the [Info] button in the "Stiffness Matrix" tab of the "Edit Surface Stiffness – Orthotropic" dialog box.

The self-weight is determined in dependence of the specific weight of the selected material as well as the values defined in the windows of the selected type of orthotropy. These values can be specified by means of the plate thickness or alternatively by a required surface load.
