i am sure you will find the book cradle to cradle very interesting. It is really an eyes opener

Dave, thanks for that input. The attitude is one that is, unfortunately, prevalent in several industries. Glad to hear that there are movements to open up things more in materials engineering. Industry associations can play a big part in such efforts.

Thanks for highlighting the fatigue failure mechanism in an new way.  Interestingly enough the same design approaches that reduce stress risers for fatigue failure generally also improve the performance of a part in heavily loaded, non-cyclical stress situations.  Good design practice often yields multiple performance benefits.

Yes, we work with ultrasonically driven dental tool manufacturing.  You can quickly reach a fatigue failure at 30KHz if you have a surface finish that can initiate crack propagation.  Excellent article.

I used to get frustrated by friends in my car hobbies discussing bolt failures of rperformance cars. Classic examples were the failures of the Corvette suspension bolts at the ends of the leaf springs. In many cases these were fatigue failures and the friends reactions were to the effect that "these are grade 8 bolts with very high tensile strength, you cannot get better than that!"  Often these high strength bolts failed from brittle crack propagation from fatigue not from gross overstress. Salt pitting corrosion was often the culprit. The strength was less importent than corrosion resistance and anodic zinc plating. Sometimes aircraft hardware with controlled geometry under the head, good thread root shape, and good hole preparation was also helpful.

The Internet of Things (IoT) is frequently defined by consumer or healthcare applications. It’s important to remember, however, that IoT offers at least as much potential to industry. One of the most promising subsets of industrial IoT is embedded vision -- or machinery that can see, interpret data, and act accordingly.
Going back to older application notes or archived CEC courses remind us of some of the most useful tricks and techniques we can use to reduce the power dissipation in an MCU-based design.
The Internet of Things is bringing smarter production processes to the factory floor and simultaneously driving data volume and diversity up -- quickly.
