This method is suitable for almost every problem in engineering. The structure to be investigated is devided into so-called finite elements by imaginary lines
and planes. The physical relation for the sought after quantity will be formulated and solved in each element under consideration of the initial and boundary conditions.
A computer derives the solution for the structure as a whole. This is done by combining the results of the individual elements.
The FEM software directly adopts the CAD data and calculates (on request) mechanical tensions, bending and buckling behavior, vibrations and resonance frequencies, and
thermal and mechanical responses to temperature impacts. |

Door of vacuum
chamber under the load of external
air pressure (~10t/m2),
Deformations not true
