Peel mechanics with large bending
International Journal of Fracture, 1977Previous small bending models for the peeling of an elastic strip from a rigid substrate are extended to large bending. Computational results obtained by an initial value method are presented. One finding is that the present large bending analysis and the conventional models based on energy considerations predict the same dependence of peel force on ...

Storage of mechanically peeled oranges and grapefruit
Postharvest Biology and Technology, 1994Abstract Oranges and grapefruit stored intact or mechanically peeled (albedo removed and cored) for up to 5 weeks at 0°C were evaluated regularly to determine if sensory differences were detectable. Additionally, affective testing was completed to assess the effect on hedonic response.

Mechanics of peeling of rubbery materials. II. Initiation and propagation of peeling
Journal of Polymer Science: Polymer Physics Edition, 1978AbstractThe peel strength of a joint with flexible materials bonded by an elastic adhesive was evaluated in relation to the fracture mechanism. It was found that initiation and propagation of peeling are governed by different mechanisms. Initiation (the formation of an initial crack) occurs when the maximum stress in the adhesive layer reaches a ...

Mechanical effects in peel adhesion test
Journal of Adhesion Science and Technology, 1989—Mechanical effects in the peel strength of a thin film have been studied both experimentally and theoretically. It has been found that the adhesion strength measured by the peel test is a practical adhesion (an engineering strength per unit width) and does not represent the true interface adhesion strength.

PERFORMANCE AND MECHANISM OF METHYLENE BLUE BIOSORPTION ON ORANGE PEEL
Environmental Technology, 2008Biosorption of Methylene Blue (MB) from aqueous solution using orange peel biosorbent was experimentally investigated. The effects of dye concentration, solution pH, salt concentration and contact time were investigated in a batch model. The results showed that adsorption equilibrium was reached within one hour at two initial MB concentrations (200 and

Tribology International, 2005
Abstract The peel test is commonly used to determine the strength of adhesive joints. In its simplest form, a thin flexible strip which has been bonded to a rigid surface is peeled from the substrate at a constant rate and the peeling force which is applied to the debonding surfaces by the tension in the tape is measured.

Peel mechanics of adhesive strips with constraints
International Journal of Fracture, 1978The peel force as a function of displacement was determined for debonding inextensible adhesive strips with an extensible boundary constraint. Using differential energy balance methods, a closed form expression for the peel force was obtained and found to be in excellent agreement with experimental studies.

RATE LIMITING MECHANISMS IN CAUSTIC POTATO PEELING
Journal of Food Science, 1972The caustic peeling rates of potatoes is considered from an analytical and experimental point of view. The analysis considers the process to be governed by the competing rates of mass transport within the potato (diffusion) and chemical reaction. The chemical reaction between caustic and chlorogenic acid is singled out for analysis since the product of

The mechanism of color fading in sunburned apple peel
Acta Physiologiae Plantarum, 2018The effect of sunburn on apple fruit is important because the appearance reduces the market value. Previous studies have shown that high temperature and strong light are the major causes for its occurrence and severity, and the color change of the peel is an obvious symptom of fruit sunburn.

Wire brushing of aluminium mechanism of “orange peeling”
Wear, 1960Abstract The brushing of aluminium by rotary nickel silver wire brushes gives surface changes due to low temperature welding, and not surface melting. This is shown by examination of the surface produced at different speeds of brushing, with and without lubrication, and by experimental and theoretical estimation of surface temperature.
