The continuous demand for charging devices in the shortest time is driving the charger market toward fast charging. On the one hand, the power delivered by these charges increases; on the other hand, their size is getting smaller and smaller, so it is necessary to design a higher power density. To meet the growing de

Airplanes to cell phones: Equipment Finds the Flaws

Sandia National Laboratories researchers in the Mechanics of Materials department utilize the new fracture testing hangers for traditional interlaminar composite fracture testing as well as advanced hybrid composite laminates, as shown here.

Tim Briggs has built a career at Sandia National Laboratories tearing and breaking things apart with his team of collaborators. Now, he's developed a fracture-testing tool that could help make everything from aircraft structural frames to cellphones stronger. Briggs has filed a patent for a device associated
