I’m now writing the monthly Science of Forming article for Metalforming Magazine – it’s a great honor to be taking over from Dr. Stuart Keeler. See my first article, The More You Know, on page 36 at http://metalformingmagazine.com/magazine/digital-issue/?/2017/Dec “Optimizing sheetmetal … Continue reading →

Tim Worstall, a contributor to Forbes magazine, recently wrote an opinion piece, “It’s Not China Or Trade That Killed The Steel Jobs But Recycling.“ The crux of the piece was that the job losses in the steel industry over the … Continue reading →

One of the challenges with direct hot forming a galvanized PHS is the risk of microcracks in the coating and an associated restricted process window. Steel company voestalpine has with their phs-ultraform® product developed a process that they have termed … Continue reading →

Nissan just announced the expanded use of an Advanced High Strength Steel (AHSS) that has a tensile strength of 1.2GPa (= 1,200MPa = 175 ksi = 175,000 psi). This follows their initial announcement in October 2011. Things we’ve learned: The … Continue reading →

We all hear frequent discussion about Advanced High Strength Steels, increased use of aluminum, and carbon fibres. Much of the discussion in automotive focuses on materials and processes to increase product strength and reduce mass.  A pamphlet published by Volvo … Continue reading →

Honda has developed a production manufacturing process that lets them join steel to aluminum skin panels. The first application of this will be on the 2014 Acura RLX, which will have an aluminum door skin joined to a steel door … Continue reading →

Through my website, someone asked about the deformation modes in sheet metal forming. My response: The three deformation modes in three-dimensional forming are draw, plane strain, and stretch. These can be visualized by imagining a circle of known diameter etched … Continue reading →

Sales of the 2013 Dodge Dart were lower than initially projected in 2012 because only manual transmissions were available at launch, with a six-speed automatic sourced from Hyundai serving as a stopgap until a promised nine-speed automatic is available. In … Continue reading →
