Load Increment

Glossary Term

The specification of load increments is primarily applied to the calculations according to the second-order analysis and the large deformation analysis: when considering large deformations, it is often difficult to find an equilibrium. If the loading is applied incrementally, it is possible to avoid instabilities.

For example, if there are two load increments specified, a half of the load is applied in the first step. It is iterated until the equilibrium is found. In the second step, the full load is then applied to the already deformed system and iterated again until the equilibrium is found.

Load increments have a negative effect on the computing time.
