If an eastbound 10-year-old car traveling at 15 miles per hour crashes head-on with an identical new car traveling west at the same speed, with all factors aside from age being equal, which car will fare the accident better? At first glance, this may seem like a familiar school child’s arithmetic problem, but it’s actually a highly sophisticated physics problem. Common sense and experience, of course, tell us that the new car is the better bet. A true scientific explanation, however, lies at the molecular level, beyond the perceptions of the naked eye—but not beyond the reach of researchers at Mississippi State University’s Center for Advanced Vehicular Systems (CAVS). These researchers’ work has already helped to provide answers to questions like the one above, and has also led to new knowledge and techniques that are beginning to redefine areas of automotive engineering and modern materials science. In addition, this research is also helping to change the fact that car crashes are the leading cause of death for Americans aged 4–34.

Road trips are an integral part of American culture. From the pioneers who expanded westward to Jack Kerouac’s classic chronicle of the Beat Generation, On the Road, Americans have always been on the move. Where would we be without Nat “King” Cole crooning about “Route 66? We’d be lost without Bob Dylan’s seminal “Highway 61.” We heed the call of the asphalt and don’t look back until we’re ready to turn around.

EnSight animation of a filled bottle analysis on a proposed design prior to mold manufacturing. Nampak R&D conducted a study where the aim was to gain an understanding of the behavior of fluid filled bottles under certain loading conditions. FEA technology was used to simulate the behavior of the bottles and to correlate the results of the analysis with physical bottles tested in the laboratory.

Glass Machinery Plants & Accessories, June 2007 issue 

A long-time EnSight user, Matthew Hyre, Senior Scientist/Physicist, Emhart Glass Research, has recently completed an article in Glass Machinery Plants & Accessories about his work with EnSight on glass containers.

In the glass container industry, two processes of forming small finished containers currently dominate: the Narrow Neck Press and Blow (NNPB) and the Blow and Blow (B&B) forming processes. In the NNPB process, pressing forms the glass container parison. Alternatively, in the B&B process the parison is blown. For most containers, the blank mould cooling strategy has been developed independent of the forming process. There are currently three primary blank cooling methodologies. In the most common system, the cooling air is blown horizontally across the blank moulds. Other cooling configurations use air flowing through vertically drilled holes in the mould.
