Is it possible to model and statically calculate solids in RFEM?

Answer

Of course, solid elements can be generated with RFEM. These are especially useful, for example, in the case of particularly shaped machine components or very thick objects or if it is no longer possible to display the object as a surface element. The calculation of solids delivers deformations, stresses and distortions.

Another application area for the solid elements is the representation of contact properties. By using a contact solid, it is possible to model the transmission conditions of connections with the properties "failure under compression" or "failure under tension" for the contact perpendicular to contact surfaces, for example. For contact parallel to surfaces, you can select the properties "failure if contact perpendicular to surfaces failed," "full force transmission," "rigid friction," "rigid friction with limit," "elastic friction," "elastic friction with limit" and "elastic solid behavior."

Contact properties between two contact surfaces can also be carried out by using surface releases. These are described in the RFEM manual:

Modeling with solid elements is also shown in the video from a Dlubal Info Day, which you can find under Links.
