RISA 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 ...
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, ...
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 ...
