Crude oil for August delivery fell 11 percent, to $128.88 a barrel last week on the New York Mercantile Exchange, the biggest one-week drop in four years. Futures had reached $147.27 a barrel on July 11, the highest since 1983. And the price of oil is going to keep dropping, says a prominent energy analyst. Edward L. Morse of Lehman predicts a plunge to $93 a barrel. Declining demand will contribute to a build-up in inventories. One of the biggest drops will come in China, which had been feeding the fire. Plus there is some new capacity coming on line. The swing in oil prices upward was more exaggerated than normal because of rising speculation on oil and other commodities by investors who no longer could find good bets in real estate, or in the stock market. Some $90 billion of new cash reportedly moved into commodity funds in the past 18 months. A drop in short-term oil price speculation will help move tags down.
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.
