Product Development - Antiterrorism

In 2012, a major multinational material science company contracted Hinman to explore whether their glazing products would be practical to use on building facade blast retrofits. The product essentially created a double façade system, adding a layer of glazing product to existing façades.

Hinman used its highly developed modeling capabilities to simulate if and how the material resisted and dissipated the effects of large blast loads.

Using the commercial finite element code LS-DYNA, Hinman applied high fidelity modeling techniques. The firm has extensive experience using LS-DYNA on projects including small component analysis, crash studies, blast analysis, and whole-building structural modeling.

For this project,  Hinman used the software’s advanced Arbitrary Lagrangian-Eulerian (ALE) functions to simulate the transfer of blast pressures through varying “gapspace” distances to ensure that the blast loading on the interior original system was reduced to acceptable levels.

From the results, Hinman offered practical guidelines for how to best implement the system and, ultimately, to expand lucrative market opportunities.
