Ann, social media, at least of the facebook kind, has already gotten old and become a worthless collection of features, as far as I am concerned. Really, it is more like "spewing data" as opposed to sharing information, and very little of communicating insights is done, from what I see. I would not miss it one speck if it were gone some morning.
The various online discussion groups are different by quite a bit, and I enjoy the physics papers weekly publication and discussions as well.
Ah, Chicago still feels warm to me, Cabe. But I know what you mean about steel. I think composites are still a mystery. We don't know yet whether they're going to catch on and we don't know the full range of applications we'll see with composites. It will be interesting.
William, corrosion usually refers to what happens when metal breaks down. Composites can certainly break down, but "corrosion" is not the correct term. They delaminate, fragment, and suffer environmental stress cracking, as we've discussed here: http://www.designnews.com/author.asp?section_id=1392&doc_id=238056 http://www.designnews.com/document.asp?doc_id=236816 http://www.designnews.com/author.asp?section_id=1365&doc_id=238200
Ann, actually, from what I have read, composites do corrode, but differently from metal.
The one other thing is that typically buildings are kept around a lot longer than aircraft or racecars, so that what happens after 30 years of weather matters on a building, while the race car is obsolete and the airplane is probably scrapped, or sold to the minor leagues.
Glad to see the reduction of wood use in architecture. But, I think that is a "no-brainer." A cow in a barn destroyed the wooden version of Chicago. Now, it's all rusty steel. Not a single fire since. Though, the city now has a cold feel to it.
William, I had the same question about damage, but I don't see why the wear problems would be much worse than what aircraft with carbon composite skins experience; in fact, they're probably not nearly as severe, since these buildings aren't speeding through the air and storms of hail, dust, and rain like planes do. Composites, of course, don't corrode like metals do.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
