RISAdhesion Map for Thin Membranes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new Tabor's parameter دˆ is defined for adhesiondelamination of thin membranes. A small دˆ corresponds to a thick, small, and stiff membrane under the influence of a longrange weak surface force, as in the Derjaguin– ...
A Preliminary Two-Dimensional Palpation Mechanics for Detecting a Hard Inclusion by Indentation of a Soft Matrix Under Large Strain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A rigid inclusion is embedded at a finite depth in a soft layer resting on a rigid substrate. A spherical indenter presses vertically onto the surface, deforming the matrix and displacing the inclusion. A subsurface inclusion ...

One-Dimensional Constrained Blister Test to Measure Thin Film Adhesion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A rectangular film is clamped at the opposite ends before being inflated into a blister by an external pressure, p. The bulging film adheres to a constraining plate with distance, w0, above. Increasing pressure expands the ...
Delamination of a Thin Film Driven by a Flat Cylindrical Shaft
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical model is derived for the delamination of a thin film from a rigid substrate by a cylindrical shaft with a flat end and finite radius. We show that, within certain limitations, a point-load model can be applied ...
Adhesion of a Cylindrical Shell in the Presence of DLVO Surface Potential
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical model is built for a micrometer size cylindrical shell adhering to a rigid surface in the presence of an electrolyte. In the presence of surface electrostatic double layers and van der Waals attraction according ...
Revisiting the Constrained Blister Test to Measure Thin Film Adhesion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thin film is clamped at the periphery to form a circular freestanding diaphragm before a uniform pressure, p, is applied to inflate it into a blister. The bulging membrane adheres to a rigid constraining plate with height, ...
Estimation of Wind Speed Distribution Using Markov Chain Monte Carlo Techniques
Publisher: American Meteorological Society
Abstract: The Weibull distribution is the most commonly used statistical distribution for describing wind speed data. Maximum likelihood has traditionally been the main method of estimation for Weibull parameters. In this paper, ...
Intersurface Adhesion in the Presence of Capillary Condensation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An elastic sphere adheres to a rigid substrate in the presence of moisture. The adhesion–detachment trajectory is derived based on the Hertz contact theory that governs the contact mechanics and Laplace–Kelvin equation ...
