The Effect of Work of Adhesion on Contact of a Pressurized Blister With a Flat Surface
… above it is modeled with no adhesion, the JKR-type of adhesion, and the DMT-type of adhesion. Several substrate heights are considered, along with several values for the work of adhesion in the JKR analysis, and several combinations of force magnitude and gap size in the DMT analysis. The …

Modelling and optimization of green pellets classification on roller screens using the discrete element method
… of these solids. According to the results, the JKR model was the one that best fitted the interactions of low resistance moist pellets among themselves and rolls surface. Exploratory simulations evaluated the sensitivity of the model to different operating conditions. The application of the …

The Effect of Adhesion on the Contact of an Elastica with a Rigid Surface
… Two adhesion models are investigated. First, a JKR-type analysis, which examines the effect of adhesion forces that exist within the area of contact between the elastica and the rigid surface, is considered. Various values for the work of adhesion are examined. A DMT-type analysis, which assumes …

Measurement of Surface and Interfacial Energies between Solid Materials Using an Elastica Loop
… the contact diameters observed in the classical JKR tests, the contact length obtained using this elastica loop technique is, in general, larger, which provides potential for applications of this technique in measuring interfacial energies between solid materials with high moduli. The contact …

A mechanically-derived contact model for adhesive elastic-perfectly plastic particles
… of the free surface with good precision. JKR type adhesion is recovered seamlessly by simply allowing the springs to `stick’ to the 1D indenter's surface. To complete the contact model an additional treatment for the bulk elastic contact regime, characterized by a rapid stiffening in the …

Synergistic Environmental Aging of Glass Reinforced Polymer Composites
… calculated using the Johnson-Kendall-Roberts (JKR) model and the Hamaker approach with the drag forces created by slow water flows. Subsequently, the particle removal mechanism was verified on an inclined unidirectional glass/epoxy surface with randomly distributed epoxy particles subjected to …
