Why Things Fail: from tires to helicopter blades, everything breaks


I'm really digging on Wired magazine's materials science coverage of late. I don't know if they're intentionally adding more reportage of materials or if it's a coincidence. I'm happy either way.

This month's issue has an article on Ford's Building 4 testing complex in which they test automotive parts - gas pedal hinges, engines, even entire vehicles - to failure and try to develop a failure analysis curve to show how long they can expect to have a part survive under typical circumstances. The article also covers Vextec - a failure analysis company - and their efforts to computerize the failure testing process, developing a way to model materials on the computer, create thousands of virtual versions of the material, and test each of them to failure without making and destroying thousands of prototypes, something that aligns wonderfully with the Materials Genome Initiative.

Good stuff here, plus it's about cars...always cool.
