Abstract: Models which can be used to calculate the internal stresses within wound rolls of web material have all been confirmed to the center winding technique to date. The mechanism by which a nip ...

Abstract: An investigation was performed, using the slow strain-rate tensile test technique, to determine whether nickel and typical nickel base alloys were susceptible to embrittlement by liquid mercury ...

Abstract: The fatigue lifetimes and fractography were compared for nickel and typical nickel base alloys of the Monel, Inconel, and Incoloy series, tested at room temperature in alternating tension in ...

Abstract: The configuration of read/write head designs in floppy disk drive units is of import as some designs witness vibration phenomena which lead to signal loss and excessive wearing of the disk ...

Abstract: A method for calculating the internal stress distribution in a wound roll subjected to a homogeneous temperature change is presented. The nonlinear constitutive behavior apparent in the stack-wise ...

Abstract: A realistic and adaptive viscoelastic model for prediction of transient wound roll stress distributions is presented. The web material is taken to be orthotropic with a nonlinear radial stiffness ...

Abstract: A method is presented for determining the two levels of instability that are associated with thin web materials traveling through process machinery. The first level of instability involves the ...

Abstract: A simple algorithm has been developed for predicting traction in web handling applications. Minimal traction exists when the minimum air film height between the roller and web is greater than ...

Abstract: An experimental study shows that the traction coefficient of friction (μT ) is a function of the predicted air film height, the roller and film surface roughness, and the static coefficient ...

Abstract: Air entrainment can become a significant problem in a web handling process line. The development of an air film between a roller and web can cause a reduction in traction. This can cause a ...
