Wrinkling prediction procedure in thin sheet metal forming processes with adaptive mesh refinement. Part 1: contact free wrinkling [PDF]
, 2001 Upon cooling, branched line defects develop in epitaxial graphene grown at high temperature on Pt(111) and Ir(111). Using atomically resolved scanning tunneling microscopy we demonstrate that these defects are wrinkles in the graphene layer, i.e. stripes

Different routes to chaos via strange nonchaotic attractor in a quasiperiodically forced system [PDF]
, 1998 This paper focusses attention on the strange nonchaotic attractors (SNA) of a quasiperiodically forced dynamical system. Several routes, including the standard ones by which the appearance of strange nonchaotic attractors takes place, are shown to be ...

Wrinkling of Orthotropic Viscoelastic Membranes [PDF]
, 2010 This paper presents a simplified simulation technique for orthotropic viscoelastic films. Wrinkling is detected by a combined stress-strain criterion and an iterative scheme searches for the wrinkle angle using a pseudo-elastic material stiffness ...

Effects of initial imperfection and mesh resolution on wrinkle and crease analyses
Nihon Kikai Gakkai ronbunshu, 2021 This study investigates the effects of initial imperfection and mesh resolution on the wrinkling and creasing. Finite element analyses are conducted to simulate compression behaviors of an incompressible Neo-Hookean elastic plane with a V-shaped notch as

Disappearance of stretch-induced wrinkles of thin sheets: a study of orthotropic films [PDF]
, 2016 A recent paper (Healey et al., J. Nonlin. Sci., 2013, 23:777-805.) predicted the disappearance of the stretch-induced wrinkled pattern of thin, clamped, elastic sheets by numerical simulation of the F\"oppl-von K\'arm\'an equations extended to the finite

Wrinkling of microcapsules in shear flow
, 2006 Elastic capsules can exhibit short wavelength wrinkling in external shear flow. We analyse this instability of the capsule shape and use the length scale separation between the capsule radius and the wrinkling wavelength to derive analytical results both

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 In the transport processes of plastic-films, wrinkling is sometimes generated due to misalignment of roller. To avoid the wrinkling, it is effective to reduce the web tension. However, under the low web tension, the traction inevitably falls as transport

Effects of the roller feed ratio on wrinkling failure in conventional spinning of a cylindrical cup
, 2011 In this study, wrinkling failure in conventional spinning of a cylindrical cup has been investigated by using both finite element (FE) analysis and experimental methods.
