In this paper, in situ experiments have been designed using the full-field deformation technique of Digital Image Correlation (DIC) to characterize non-uniform shrinkage in thermoplastic polymers commonly used in traditional and emerging molding processes. These experiments are capable of characterizing the differences in strains that develop due to thermal gradients and stiction as the polymer...

The technique of laser micro-processing has recently found several important and widespread applications in the manufacturing of disk-drive components. Examples provided here include the cleaning of surface contaminants, the formation of “nano-bumps” on disk surfaces for controlled surface texturing or for making nanometer-height standards, and the micro-bending of magnetic head sliders for fli...

An analysis of stick-slip behavior and convergence trajectories in the feedback-controlled motion systems with discontinuous Coulomb friction is provided. A closed-form parameter-dependent stiction region, around an invariant equilibrium set, proved to be always reachable globally attractive. It shown that only asymptotic can achieved, at least one but mostly infinite number consecutive cycles,...
