Elastic Surface Foundation

Glossary Term

An elastic surface foundation represents an elastic support of all 2D elements of a surface.

An elastic surface foundation is used for an elastic support of surfaces. As a support or spring, you can define the spring constants Cu,x/Cu,y/Cu,z. The direction of the support refers to the local surface axes x, y and z.

The unit kip/ft³ describes the force, which — for example, in the case of Cu,z — is required to shift a surface of one square meter by one meter in the z‑direction (hence ft³).
