Engineering high-reliability W80-4 components

Radar is advancing at historic speed. How engineers are setting the pace.

The Engineering Science research area at Sandia leads engineering transitions in advanced, highly critical systems by integrating theory development, experimental discovery and diagnostics, modeling, and computational approaches to refine our understanding of complex behavior in engineered systems.

Why Our Work Matters

Revolutionizing the fundamental understanding of complex engineered systems can lead to enhancements that will bolster our national security stance for decades to come.

Our Unique Value

We do leading-edge work on physical phenomena at the continuum and near-continuum scale, and our engineering expertise in national security systems is second to none. We have foundational knowledge across multiple disciplines, including solid mechanics, fluid mechanics of reacting and nonreacting systems, structural dynamics, thermal and combustion sciences, aerodynamics, shock physics and energetics, and electromagnetic sciences. Sandia has corporate expertise in materials sciences, nanosciences, and microsciences, and we have large-scale, complex test capabilities, including high-performance computing and world-class modeling, simulation, and visualization capabilities.
