Adhesive bonding of steel structures may make them even stronger, according to a paper from Dow Automotive engineer Mansour Mirdamadi. Dow chemists have optimized the company's fracture toughened, one-component epoxy adhesives for use with AHSS. These highest-performing adhesives in this class typically have a modulus above 1,000 MPa and impact resistance across a wide temperature range (-40 to 80C). In his presentation, Mirdamadi describes a study that examined the role of structural adhesives in improving side-impact crash performance on a mini-van in IIHS tests. The results showed that an adhesive-bonded B-pillar structure offered a 5.4 mm intrusion improvement compared to a baseline design that uses no adhesive to supplement welding. In the same paper, he also lays out the significant contributions of fracture toughened adhesives to body stiffness and NVH.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
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.
