Are you looking for advice on bar steel fatigue? The American Iron and Steel Institute is starting up a blog on that subject for materials engineers, application engineers, FEA simulation experts, as well as OEM and supplier design engineers. The first post covers the topic Does Grain Refining Practice Affect Fatigue Properties? The post looks at strain life data for aluminum, niobium and vanadium that are used for grain refinement in medium carbon steels. The post comes from blog administrator Tom Oakwood, a PhD metallurgical engineer with 40 years experience. He was one of the founding members of the AISI Bar Fatigue Database.
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.
