Extreme Loading® for Structures Software or ELS, is an advanced non-linear dynamic structural analysis software tool designed with the practicing structural engineer in mind. ELS 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 utilizes a non-linear solver based on the Applied Element Method (AEM) a derivative of the Finite Element Method (FEM) and the Discrete Element Method (DEM).
This allows ELS is to automatically analyze structural behavior during elastic and inelastic modes including the automatic yielding of reinforcement, detection and generation of plastic hinges, buckling & post-buckling, crack propagation, membrane action & P-Delta effect, and separation of elements.
The resulting debris and impacts with structural elements are also automatically analyzed and stress redistribution is inherently calculated.a
