Introduction Wrinkle ridges are prominent structures mapped throughout Mars where they accommodate shortening above thrust faults due to planet-scale loading of the Tharsis rise and other features. Solis Planum contains some of the most distinct and well studied arrays of wrinkle ridges on Mars and is a focus of our work. Many previous studies have conducted modeling of these wrinkle ridges in ...

Neck wrinkles commonly develop owing to the aging process. However, recently, the number of patients with neck wrinkles has been increasing. Also, an increasing number of young patients have presented with this condition, possibly because of the effect of the head-down posture that they adopt when using their computer or smartphone. We report two cases of young adults with a prominent neck wrin...

Introduction: We undertook axial surface mapping of selected wrinkle ridges on Solis Planum, Mars in order to assess the subsurface geometry of blind thrusts proposed to exist beneath them. This work builds on previous work [1] that defined structural families of wrinkle ridges based on their surface morphology in this region. Although a growing consensus exists for models of wrinkle ridge kine...

In anti-wrinkle finishing, the crosslinking degree of fabric is mainly determined by wrinkle recovery angle, stiffness, and viscosity, these indicators can only reflect finishing effect from a macro perspective, which cannot whether sufficient, it difficult to quantify degree. this paper, we combined Kjeldahl method with Arrhenius formula proposed analyze dimethyloldihydroxyethyleneurea (two-di...

A thin metallic film deposited on a compliant polymeric substrate begins to wrinkle under compression induced in curing process and afterwards cooling of the system. The wrinkle mode depends upon the thin film elasticity, thickness, compressive strain, as well as mechanical properties of the compliant substrate. This paper presents a simple model to study the modulation of the wrinkle mode of t...

Typical bilayer wrinkle systems employ soft elastomers as the substrates. In contrast, shape memory polymers have recently emerged as attractive alternatives. Besides the shape fixing capability, shape memory polymers distinguish from elastomers in that they are rigid at room temperature, but experience significant modulus drop upon heating. We hereby report unique aspects of shape memory polym...

Facial wrinkles are an undesirable outcome caused by extrinsic photodamage and intrinsic aging processes. Currently, no effective strategies are known to prevent facial wrinkles. We assessed the beneficial effects of bee-venom serum on the clinical signs of aging skin. Our results show that bee-venom serum treatment clinically improved facial wrinkles by decreasing total wrinkle area, total wri...

Complex wrinkle patterns have been observed in various thin film systems, typically with integrated hard and soft materials for various applications as well as in nature. The underlying mechanism of wrinkling has been generally understood as a stress-driven instability. On an elastic substrate, equilibrium and energetics set the critical condition and select the wrinkle wavelength and amplitude...

This paper presents a nonlinear mathematical model for evolution of wrinkle patterns of an anisotropic crystal film on a viscoelastic substrate layer. The underlying mechanism of wrinkling has been generally understood as a stress-driven instability. Previously, theoretical studies on wrinkling have assumed isotropic elastic properties for the film. Motivated by recent experimental observations...
