Not sure if I used the right photo or not. I also uploaded Hearstbuilding01.JPG, and Hearstbuilding03.JPG as well. --Coro 00:27, 4 Apr 2005 (UTC)
— Looks like stone?
Shot-peened aluminium sheet, for example, resembles white stone, and was used in the expansion of the Hearst Memorial Mining Building at the University of California, Berkeley.
If you follow the link to the mining building page it specifically says that the aluminum sheet and modern design were chosen to separate the new part of the building from the old, not because they look alike. And they don't look alike, anyway, see the pic. Romana 19:57, 10 May 2007 (UTC)
I'd like to see a before and after comparison shot of a smaller part. The building doesn't do anything for me, it's just... a building. Karanne (talk) 02:31, 15 August 2008 (UTC)

[edit] source material
Shotpeener.com includes the publication, The Shot Peener. Although the website and magazine are produced by a company that also makes controls and gages for shot peening, many articles are written by academic researchers and other unbiased authors. It should be watched for self-promotional material but not dismissed because the publisher is in the business. Wilhkar (talk) 16:59, 27 February 2010 (UTC) Wilhkar
[edit] Grinding stress
I'm having a bit of heartburn with this sentence: "Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses."
I suggest the following instead: "Shot peening is often called for in aircraft repairs to replace the compressive layer lost by the removal of basis material.” (Or something like that)
The following information is based on my working knowledge of aircraft repair and overhaul. I realize it needs to be sourced and may count as independent research.
Shot peening is used extensively in aircraft repairs. However, it is used for fatigue life extension. Repaired areas (blended, ground etc.) have the compressive layer removed, so it’s important to put it back. As for residual stress after grinding, that was mitigated with a stress relief bake. However, we found it to be un-necessary and no longer perform that additional processing step. Alister 77 (talk) 18:47, 21 December 2010 (UTC)
