To facilitate the modeling of special mechanical properties, the program offers spring elements. They can be used to model numerous effects, including spring deflection, plastic joints, contact and tearing, etc. in a structure. Spring elements are supported in static as well as dynamic calculations.
| The spring elements are directly entered between two nodes in the structure. For every degree of freedom, a separate characteristic curve can be defined. |

Spring Exhibiting Tear Behavior
In the illustration below a spring element was entered with the characteristics as shown. The spring only works under tension and exhibits a plastic behavior if a force of 50 kN or more is applied. As soon as the yield strength of 6 cm is reached, the spring tears.
The animation documents the system behavior for a load increase beyond the yield strength:
