Geometry and physics of wrinkling

WebFeb 20, 2003 · Classical theory can predict where wrinkles will occur, but their amplitude and wavelength–and the best chance to eliminate them–has proven more difficult. Now, in the 21 February print issue of PRL, a team discovers a general law that quantitatively predicts the size, shape, and structure of wrinkles that appear on any thin film. WebMar 1, 2024 · This paper presents a new experimental methodology for determining the formability limits by wrinkling in sheet metal forming using Yoshida buckling tests (YBTs). The YBT has been the most used formability test by the scientific community to determine the occurrence of wrinkling, on the one hand, due to its simple clamping configuration …
