Since being created to help car manufacturers in the 1950s, fatigue management software has developed from being an in-house pet project to a viable commercial product. These days, many large ...

A typical microstructure (grain structure at the micron scale) of metallic material. (Courtesy: J Stinville) The tiniest defects in a metal can cause it to fail, but predicting when this so-called ...

SAE International Journal of Materials and Manufacturing, Vol. 7, No. 3 (June 2014), pp. 545-552 (8 pages) ABSTRACT Advanced high strength steels (AHSS) offer a good balance of strength, durability, ...

(Santa Barbara, Calif.) -- Take a wire paperclip. Now, bend it back and forth in the same spot 15, maybe 20 times. Chances are the paperclip will have broken before you finish. This is due to what's ...

First it was self-healing polymers. Then it was self-healing concrete. Now we have self-healing metals. A team of scientists at the Sandia National Laboratories in New Mexico recently observed a ...

Fatigue life is a key concern in welded-steel frames for mobile equipment that experience large and varying dynamic loads. For engineers who design welded-steel structures subject to dynamic loading, ...

Solid-state lithium batteries fail for the same reason over-bent paperclips snap – metal fatigue in the anode itself, according to a new study. The findings, which show that this fatigue follows ...
