Direct numerical simulations of three-dimensional surface instability patterns in thin film-compliant substrate structures [PDF]
Scientific Reports, 2021 A comprehensive numerical study of three-dimensional surface instability patterns is presented. The formation of wrinkles is a consequence of deformation instability when a thin film, bonded to a compliant substrate, is subject to in-plane compressive ...

Surface Instability of Icicles [PDF]
Physical Review E, 2002 Quantitatively-unexplained stationary waves or ridges often encircle icicles. Such waves form when roughly 0.1 mm-thick layers of water flow down the icicle. These waves typically have a wavelength of 1cm approximately independent of external temperature,

Surface Instability in Windblown Sand [PDF]
Physical Review E, 1999 We investigate the formation of ripples on the surface of windblown sand based on the one-dimensional model of Nishimori and Ouchi [Phys. Rev. Lett. 71, 197 (1993)], which contains the processes of saltation and grain relaxation. We carry out a nonlinear

Tumour angiogenesis as a chemo-mechanical surface instability. [PDF]
Sci Rep, 2016 The hypoxic conditions within avascular solid tumours may trigger the secretion of chemical factors, which diffuse to the nearby vasculature and promote the formation of new vessels eventually joining the tumour.

Surface Instability of Sheared Soft Tissues [PDF]
Journal of Biomechanical Engineering, 2008 When a block made of an elastomer is subjected to a large shear, its surface remains flat. When a block of biological soft tissue is subjected to a large shear, it is likely that its surface in the plane of shear will buckle (appearance of wrinkles). One factor that distinguishes soft tissues from rubberlike solids is the presence—sometimes visible to ...

Nanomaterials, 2022 Surface wrinkling instability in thin films attached to a compliant substrate is a well-recognized form of deformation under mechanical loading. The influence of the loading history on the formation of instability patterns has not been studied.

Instability of Compacted Residual Soil
Geosciences, 2021 Static liquefaction of loose sands has been observed to initiate at stress ratios far less than the steady-state stress ratio. Different collapse surface concepts largely based on undrained triaxial test results have been proposed in the literature to ...
