Thin-film peeling-the elastic term
WebThe work of Kendall and Gent [3, 4] explained the dependence of peeling force on peeling angle, work of adhesion and the modulus of the adhesive tape. Although the measurement of peeling strength has been widely studied, few experiments have explored the effect of humidity and temperature on peel strength. Web10 Apr 2024 · The practical problem of free formaldehyde pollution in the plywood industry is that polyethylene films have been shown to be able to replace some urea–formaldehyde resins for wood adhesives. To broaden the variety of thermoplastic plywood, reduce the hot-press temperature, and save energy consumption, an ethylene–vinyl acetate (EVA) film …

Web19 Jul 2024 · Peeling in viscoelastic materials has been studied experimentally for many years mostly at 90 or 180 degrees angle, and typically the classical Rivlin energy balance equation is used to obtain a ... Web1 May 2024 · We will analyze the 90° peeling of an elastic film on a rigid substrate subject to different interfacial cohesive laws and establish a general solution to the maximum detachment force. In this analysis, finite element simulations will be performed to extend and validate theoretical predictions.
Web1 Aug 2011 · We report the design, fabrication and characterization of micromachined Parylene structures for self-sealing liquid encapsulation applications. Automatic sealing is enabled through the use of an integrated annular-plate stiction valve which greatly reduces device footprint over in-plane configurations. We achieve automatic wafer-level liquid … Web10 Aug 2012 · The force between an elastic beam and a rigid body is investigated by considering shear force and total energy, and is obtained as a function of the displacement of the elastic beam. The proposed theory is different from Kendall’s thin-film peeling theory in terms of the elastic energy.
Web1 Jan 2024 · The present paper deals with the peeling of an elastic thin tape from a viscoelastic substrate. A previous investigation of the authors has disclosed several physical aspects of such phenomenon by focusing the attention on an ideal viscoelastic substrate with one-single relaxation time. WebConformal organic thin-film transistors (OTFTs) that can adhere seamlessly to human skin or within the body are highly desirable for future large-scale low-cost wearable and implantable electronics. However, the fabrication of high-performance elastic dielectric-based conformal OTFTs is still a huge challenge, because it is difficult to ...
Web11 Sep 1975 · This elastic term, tending to reduce the adhesion force, can only be significant in two instances: for materials which can support stresses approaching the elastic modulus without fracturing, and for very small peel angles. Experiments using rubber peeling from glass over a range of peel angles support the theory.
Web– the forcible peeling of a film from its substrate as a means of evaluating the adhesion energy of the interface between the film and the substrate. This chapter deals with the transverse or out-of-plane deflection of a thin film, and it includes quantitative descriptions of the phenomena associated with the buckling, bulging or peeling of a ... melon beauty productsWebA shaft-loaded blister test has been developed to measure the interfacial energy W of a thin flexible polymeric film adhered to a rigid substrate.
