A tempered glass bottom on a new cantilevered walkway will allow visitors to the Grand Canyon to look 4,000 feet straight down to the Colorado River. It's 10 feet wide and extends 70 feet from an anchor rock. The Hualapai Indian Tribe's Glass Walkway features 90 tons of glass and a million pounds of steel. A grand opening is set for March. Another footnote for scientists: According to a blog (citing an AP report), the Bush Administration supposedly won't let park officials reveal their estimate of the age of the park for fear of offending creationists. . Seems a little far fetched to me.
A new process for laser-welding large-scale, steel-aluminum foam sandwich structures for lightweighting ships, which eliminates intermetallic phase, has been demonstrated.
A major advance in repairing composite structures combining robots and lasers bodes well for commercial aircraft such as the Boeing 787 Dreamliner and Airbus A350XWB, which contain composites in large proportions of their structures.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
