Extreme Loading® for Structures (ELS) is an advanced non-linear structural analysis software tool that allows structural engineers to study the 3D behavior of structures through both the continuum and discrete stages of loading. This includes static and dynamic loads such as those generated by blast, seismic events, impact, progressive collapse, and wind. ELS’s nonlinear Applied Element Method (AEM) solver analyzes structural behavior during elastic and inelastic modes including the automatic detection and generation of plastic hinges, buckling, cracks, and separation. In addition, resulting motion and impact of debris structural elements is also automatically analyzed with stress redistribution inherently calculated.
