Blast Walls and Barricades
The ability of buildings, bridges, dams, and other critical infrastructure to withstand catastrophic events such as
earthequakes, strikes, or blasts is of growing concern. ES3 provides predictive computations simulations of the response
of reinforced concrete and steel structures to potential these catastrophic events. Our simulations assist in determining
asset vulnerability, placement of blast walls and barricades, or modification of operation to ensure the structures are
kept safe. Continuum-based models, which homogenize material behavior, are inherently incapable predicting post failure
mode behavior. Most materials are not homogenous when considered at the sufficiently small dimensional scale (micro- and meso-scale).
Modeling of this heterogeneous character enables ES3 to predict strain localization, crack initiation, and crack propagation,
which, in turn strongly influences the ultimate failure modes of a structral system.
