The formation of waviness on the working surfaces bearing parts is associated with fluctuations in size cut layer metal and changes components cutting force. Laplace operators were used to model centerless grinding system based construction transfer function characteristic equation. It was found that depends position hodograph movement vector center part complex plane, which turn geometric para...

It is well established that fiber waviness in continuous fiber-reinforced polymer composites a defect rather than an aesthetic flaw, as it potentially leads to severe knockdown of the mechanical properties. Consequently, desirable minimize or prevent during processing. This research explored experimentally influence tool material, release media and laminate size on formation in-plane C/PEEK con...

The presence of fiber waviness defects is well-known to reduce the compressive strength. A FE model was established and results failure load mode were compared with test demonstrate validity accuracy. influence two parameters L offset Angle θ defect studied. simulation show that compression increases increasing at constant A/H for convex concave fold by 33.0% 20.1% respectively, but there no si...

In rotordynamic simulations, rolling element bearing waviness is often accounted using nonlinear models that are solved with a numerical integration scheme in time domain. This approach generates accurate system response, but the method limited terms of computational efficiency. study proposes two novel methods for solution responses caused by excitation frequency domain, and compares result pr...

Capillary Wetting of Colloidal Monolayers In article number 2208402, Shin-Hyun Kim and co-workers study capillary wetting colloidal monolayers by a limited volume molten polymer, which enables the production complex wavy surfaces with controlled waviness. The directional metal deposition on 3D structures develops both plasmonic diffraction colors are otherwise difficult to achieve conventional ...
