Loading cycle and qualitative fiber shapes for a fiber completely clamped to a laterally unconstrained and laterally constrained support. (a) Initial configuration. (b) Fiber tip at angle , side contact begins, tip no longer slides relative to opposing substrate. (c) Maximum value of preload . (d) Preload relaxed to continuous load , which can be negative.
Deformation of an elastic fiber, completely clamped vertically at its base, making contact with an adhering substrate over a length .
Dependency of nondimensional contact length on applied load parameter ; curves , , and correspond to a laterally unconstrained support with , 35.4, and 54.1, respectively; curves , , and correspond to a laterally constrained support with , 35.4, and 54.1, respectively. The × denotes spontaneous detachment.
Dependency of nondimensional contact length on inclined fiber slope for zero applied load. The curve labels are the same as for Fig. 3, with the addition of curve , which corresponds to a laterally unconstrained support with .
