Video: Robot Hitchhikes Across Canada
Blog 8/19/2014 27 comments If you see a hitchhiker along the road in Canada this summer, it may not be human. Thatís because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX Reveals 3D-Printed Rocket Engine Parts
Engineering Materials 8/19/2014 9 comments SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Top Myths About Stainless Steel
Guest Blogs 8/6/2014 50 comments The properties of stainless steel make it well suited for a wide range of applications, but many of the things engineers think they know about stainless steel arenít true.
Can Plastic Bearings Outperform Metal Ones?
Blog 8/6/2014 7 comments Plastic bearings are replacing metal in some pretty tough jobs. Sometimes they're equally effective and reliable, and sometimes they actually outperform those parts. We'll tell you all about how this is possible in an upcoming Design News Focus on Fundamentals course.
Update: Intelligent Composites for Structural Monitoring
Engineering Materials 8/5/2014 5 comments Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
