Solvent induced transition from wrinkles to creases in thin film gels with depth-wise crosslinking gradients†‡
We investigated solvent induced transition of surface instability from wrinkles to creases in poly(2-hydroxyethyl methacrylate) (PHEMA) gels with depth-wise crosslinking gradients. The mode of surface instability and morphology of surface patterns was found to be dependent on the equilibrium linear expansion, which was a function of crosslinker concentration and the solvent–polymer interaction....
متن کاملCreases on the interface between two soft materials.
Theory and experiment are presented to show that an interface between two soft materials under compression can form creases, a type of bifurcation distinct from wrinkles. While creases bifurcate from a state of flat interface by a deformation localized in space and large in amplitude, wrinkles bifurcate from a state of flat interface by a deformation nonlocal in space and infinitesimal in ampli...
متن کاملComparative clinical assessment of two nasolabial hyaluronic acid fillers: A double-blind, randomized controlled trial
Background: Various fillers have been used for the correction of nasolabial folds. This study investigated the efficacy and safety assessment of two hyaluronic acid (HA) fillers on moderate nasolabial folds. Methods: This study randomized 10 volunteers, aged 35 to 49 years, with moderate nasolabial folds. Volunteers received injections of HA A and HA B gels into the right or left skin folds. Th...
متن کاملCreases in soft tissues generated by growth
Soft tissues growing under constraint often form creases. We adopt the model of growth that factors the deformation gradient into a growth tensor and an elastic deformation tensor, and show that the critical conditions for the onset of creases take a remarkably simple form. The critical conditions are illustrated with tubes of tissues growing either inside a rigid shell or outside a rigid core....
متن کاملBifurcation Diagrams for the Formation of Wrinkles or Creases in Soft Bilayers
Subject to compression, elastic materials may undergo bifurcation of various kinds. A homogeneous material forms creases, whereas a bilayer consisting of a stiff film and a compliant substrate forms wrinkles. Here, we show several new types of bifurcation behavior for bilayers consisting of films and substrates of comparable elastic moduli. Depending on the ratios of moduli and thicknesses of t...
