Extreme Loading for Structures (ELS) is commercial structural-analysis software based on the
applied element method The applied element method (AEM) is a numerical analysis used in predicting the Linear continuum, continuum and Discrete mathematics, discrete behavior of structures. The modeling method in AEM adopts the concept of discrete cracking allowing it to ...
(AEM) for the automatic tracking and propagation of cracks, separation of elements, element collision, and collapse of structures under extreme loads.
AEM combines features of
Finite element method
The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat ...

Discrete element method
A discrete element method (DEM), also called a distinct element method, is any of a family of numerical methods for computing the motion and effect of a large number of small particles. Though DEM is very closely related to molecular dynamics, t ...
simulation with its own solver capabilities for the generation of PC-based structural analysis.
History
2003
* Research and development related to the software begins with the formation of Applied Science International. The first release of ELS appears in the form of 2D analysis with structures modeled, loading scenarios applied, and results viewed.
2008
* Version 2.0 allows users to perform 3D analysis, though modeling is largely limited to 2D and restricted 3D functionality.
* The United States Department of Homeland Security assigns ELS Designation Status for Anti-terrorism under the SAFETY Act.
2009
* ELS version 3.0 is released with complete 3D functionality.
