Extreme Loading for Structures Developer Applied Science International Stable release ELS Version 3.0 / September 3, 2009; 16 years ago (2009-09-03) Operating system Windows Type Simulation software Website www.extremeloading.com

**Extreme Loading for Structures** (**ELS**) is commercial structural-analysis software based on the [applied element method](/source/Applied_element_method) (AEM) for the automatic tracking and propagation of cracks, separation of elements, element collision, and collapse of structures under extreme loads.[1] AEM combines features of [Finite element method](/source/Finite_element_method) and [Discrete element method](/source/Discrete_element_method) 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.[2]

### 2009

- ELS version 3.0 is released with complete 3D functionality.
