“…In the next section, this claim is supported by a simplified FEM calculation for a non-adhesive, tangential contact between a finger and smooth rigid plate, taking into account non-linear elastic material behavior. Note, that very recently a similar finding concerning a smooth contact between a soft cylindrical cap and a rigid plate was made by Mergel et al (2020). They have shown that the contact length decreased under tangential shear even in the absence of adhesion.…”

Frontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

“…Based on the two models, the peeling behaviors of the strip that simulates the peeling of the spatula were explored again, and some conclusions that are similar to the gecko adhesion could be obtained: the sliding of the spatula near the peeling front can pre-stretch the spatula, thereby increasing the peeling force; the peeling of the spatula exists the critical detachment angle; the spatula can be easily detached from the substrate by changing the shaft angle and adopting a vertical peeling method [59,60]. Although the two models have been extended to three dimensions by researchers [61], the assumption that the static friction threshold based on the macroscopic measurement is consistent with the resistance for kinetic friction still needs to be verified on the local contact area. In addition, although the two models couple with the adhesion and the friction, as the researchers emphasized, the tangential friction is dependent on the normal adhesion rather than that the normal adhesion is dependent on the tangential friction in the two coupled models, which is just the opposite of the mechanism of frictional adhesion of gecko's foot.…”

Gecko-Like Dry Adhesive Surfaces and Their Applications: A Review

2021

View full text Add to dashboard Cite

Gecko has the ability to climb flexibly on various natural surfaces because of its fine layered adhesion system of foot, which has motivated researchers to carry out a lot of researches on it. Significant progresses have been made in the gecko-like dry adhesive surfaces in the past 2 decades, such as the mechanical measurement of adhesive characteristics, the theoretical modeling of adhesive mechanism and the production of synthetic dry adhesive surfaces. Relevant application researches have been carried out as well. This paper focuses on the investigations made in recent years on the gecko-like dry adhesive surfaces, so as to lay the foundation for further research breakthroughs. First, the adhesion system of gecko’s foot and its excellent adhesive characteristics are reviewed, and the adhesive models describing the gecko adhesion are summarily reviewed according to the different contact modes. Then, some gecko-like dry adhesive surfaces with outstanding adhesive characteristics are presented. Next, some application researches based on the gecko-like dry adhesive surfaces are introduced. Finally, the full text is summarized and the problems to be solved on the gecko-like dry adhesive surfaces are prospected.

“…Although these early models are limited to simple, normal-load scenarios, they inspired numerous subsequent researches that offer an extension to mixed-load schemes involving normal and tangential loads. We also note a few recent achievements based on finite element continuum contact models that incorporate mixed mode constitutive interface laws [13,17,18], all of which can describe the reaction of adhesive interfaces under complex load involving tension and shear. In this work, in order to simulate complex interface behaviours with reversible adhesion, we adopt the Raous-Cangémi-Cocou (RCC) model [19][20][21][22], which over the years has confirmed its robustness in dealing with adhesive frictional contact.…”

An extended, ready-to-implement 3D model for quasi-industrial problems of contact with friction and recoverable interface adhesion between soft material is formulated using the Raous-Cangémi-Cocou (RCC) interface model and a bi-potential based resolution method. According to the RCC description, the recoverable adhesive interface behaviour derives from a free surface energy and a surface dissipation pseudo-potential. The obtained interface law describes both the de-bonding process of adhesive links due to tangential and normal interface deformation, and reversely, the bonding process that takes place when two surfaces approach close enough. We then propose an associated formulation coupling 3D extended interface law and Blatz-Ko hyperelastic material, that enables modelling large deformations of foam type soft matters under conditions of contact and friction with recoverable adhesion. In the end, the subsequent local contact nonlinear equations are solved using a Newton-like algorithm within the bi-potential framework. Numerical examples are performed to demonstrate the capacity of the proposed approach.
