Thin explosive films provide snapshot of how detonations start

March 4, 2021 • ALBUQUERQUE, N.M. — Using thin films — no more than a few pieces of notebook paper thick — of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow. Sandia is the only lab in the U.S. that can make such detonatable thin films....

Modeling terrorist behavior with Sandia social-cultural assessments

January 24, 2019 • ALBUQUERQUE, N.M. — Part of what makes terrorists so frightening is their penchant for unpredictable, indiscriminate violence. One day they could attack a global financial center. And the next they could hit a neighborhood bike path. A team of Sandia social-behavioral scientists and computational modelers recently completed a two-year effort,...

Sandia computer modeling aids solder reliability in nuclear weapons

December 19, 2017 • ALBUQUERQUE, N.M. — Solder isn’t the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability. “Computational...

Research at Sandia looking at how brittle materials fail

February 13, 2017 • ALBUQUERQUE, N.M. — If you want to see what happens if your phone falls onto concrete, you can actually drop it or let an engineer work out the consequences in advance. Odds are you’ll go with the engineer. Figuring out how brittle materials inside a device behave, and fail, is...

Techniques could create better material, design in high-consequence uses

September 23, 2015 • ALBUQUERQUE, N.M. — Imagine a table with sinuous legs resembling the twisting shape of an inverted swamp cypress trunk. Those flowing legs might make the table stronger, better able to handle whatever someone piles on it. Sandia National Laboratories researchers believe such organically shaped designs, achieved through a technology called...
