An Introduction to Stress Analysis and Transducer Design Using Strain Gauges

The usual way of assessing structural parts of machines, buildings, vehicles, aircraft, etc. is based on strength of material calculations.

A New Paradigm for Mid-Lifecycle Design Changes

For decades, the general belief was that the replacement of key components during the mid-lifecycle design refresh of complex electromechanical systems was simply too costly and burdensome — and that any changes in product design would simply need to wait until the next generation.

Earth-Sized Exoplanet Discovered via Observatory Data

The National Science Foundation-funded Gemini observatory helped confirm the first potentially habitable Earth-sized exoplanet. Researchers say this discovery is unique because the planet, called Kepler-186f, resides in a temperate region around its host star where water could exist and could possibly sustain life. Earth-sized planets are very difficult to detect because of contrast with their host stars.

Wind Tunnel Tests Support Improved Design of B61-12 Bomb

Sandia National Laboratories has finished testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel. The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system.

Testing Composite Structures for Stronger Bridges

The J. Lohr Structures Laboratory at South Dakota State University helps companies develop new materials and products — self-consolidating concrete columns and pre-stress concrete bridge girders — that bridge a physical gap. Over the past decade, researchers have conducted structural testing on large- and full-scale test specimens for private companies and government entities.

With New Sensors, NASA's Morpheus Preps to Land on its Own

A test flight will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land. Mounted to an uncrewed prototype lander called Morpheus that flies autonomously several hundred feet above the ground, the sensor system will have 10 seconds to do its work. The sensor system is a 400-pound set of computers and three instruments called ALHAT (Autonomous Landing and Hazard Avoidance Technology).
