Apparently, the engineers who designed the rotating amphitheater at the Hoover Dam took their proximity to Las Vegas too seriously. They took a gamble and designed the turntable, which holds 450 people, without using finite element analysis. Bad idea. Soon after the amphitheater opened, the turntable broke down. Engineering consultant David Dearth got a U.S. Department of Interior contract to determine the cause of the failure. He did use FEA, specifically MSC.visualNastran for Windows. Finding: Use stronger steel and bigger axle.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
