Extreme Loading for Structures (ELS) is commercial structural-analysis software based on the applied element method (AEM) for the automatic tracking and propagation of cracks, separation of elements, element collision, and collapse of structures under extreme loads.{{cite journal |author1=Meguro, K. |author2=Tagel-Din, H. | title = Applied element method for structural analysis: Theory and application for linear materials | journal = Structural Engineering/Earthquake Engineering | volume = 17 | issue = 1 | pages = 21–35 | publisher = Japan Society of Civil Engineers | location = Japan | year = 2000 | url = http://sciencelinks.jp/j-east/article/200014/000020001400A0511912.php | id = F0028A | accessdate = 2009-08-10 | url-status = dead | archiveurl = https://web.archive.org/web/20120229032846/http://sciencelinks.jp/j-east/article/200014/000020001400A0511912.php | archivedate = 2012-02-29 }} AEM combines features of Finite element method and 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.{{cite web | author = DHS | title = SAFETY Act Designation Status Listing | publisher = Department of Homeland Security | url = https://www.safetyact.gov/DHS/SActHome.nsf/Designations?ReadForm | accessdate = 2009-08-10 | archive-url = https://web.archive.org/web/20090814034718/https://www.safetyact.gov/DHS/SActHome.nsf/Designations?ReadForm | archive-date = 2009-08-14 | url-status = dead }}

ELS version 3.0 is released with complete 3D functionality.

Academic institutions

More than 20 universities and academic institutions are currently involved in research and development projects resulting in the creation of publications on topics related to the Applied Element Method and Extreme Loading for Structures.{{cite web | author = AEM Website | title = Applied Element Method - Publications Library | publisher = AppliedElementMethod.com | url = http://www.appliedelementmethod.com/Publications.aspx | accessdate = 2009-08-12 | archive-url = https://web.archive.org/web/20090808151025/http://www.appliedelementmethod.com/Publications.aspx | archive-date = 2009-08-08 | url-status = dead }} Academic institutions working with ELS include:
