Ageing behaviour of folded joints produced by fusion bonding of an outer metal sheet and an inner organic sheet [PDF]
Journal of Advanced Joining ProcessesAdhesive hemming is a process used in the automotive industry to join two metal sheets with good structural performance and good optical appearance of the rim. A new approach is to replace the inner metal sheet by a fibre-reinforced thermoplastic polymer

Folded Sheet Versus Transparent Sheet Models for Human Symmetry Judgments
Symmetry, 2011 As a contribution to the mysteries of human symmetry perception, reaction time data were collected on the detection of symmetry or repetition violations, in the context of short term visual memory studies. The histograms for reaction time distributions are rather narrow in the case of symmetry judgments.

Epithelial sheet folding induces lumen formation by Madin-Darby canine kidney cells in a collagen gel. [PDF]
PLoS ONE, 2014 Lumen formation is important for morphogenesis; however, an unanswered question is whether it involves the collective migration of epithelial cells. Here, using a collagen gel overlay culture method, we show that Madin-Darby canine kidney cells migrated ...

Comparative Study of Crumpling and Folding of Thin Sheets [PDF]
Physical Review Letters, 2013 Crumpling and folding of paper are at rst sight very di erent ways of con ning thin sheets in a small volume: the former one is random and stochastic whereas the latest one is regular and deterministic. Nevertheless, certain similarities exist. Crumpling is surprisingly ine cient: a typical crumpled paper ball in a waste-bin consists of as much as 80 ...

Many dissimilar NusG protein domains switch between α-helix and β-sheet folds
Nature Communications, 2022 Folded proteins are composed of secondary structures, α-helices and β-sheets, that are generally assumed to be stable. Here, the authors combine computational prediction with experimental validation to show that many sequence-diverse NusG protein domains

Buildings, 2019 The article concerns a parametric description of unconventional building forms roofed with folded sheeting transformed elastically into shells. The description supports the designer in the search for attractive forms and a rational use of materials.

Research on Mechanical Properties of V-Type Folded Core Sandwich Structures
Aerospace, 2022 A folded core is a three-dimensional configuration formed by folding a flat sheet of paper. Similar to foam and honeycomb, folded cores are widely used in aerospace as the cores for sandwich structures due to their excellent mechanical properties and ...

Periodic folding of viscous sheets
Physical Review E, 2003 The periodic folding of a sheet of viscous fluid falling upon a rigid surface is a common fluid mechanical instability that occurs in contexts ranging from food processing to geophysics. Asymptotic thin-layer equations for the combined stretching-bending deformation of a two-dimensional sheet are solved numerically to determine the folding frequency as
