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.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
