Vibratory Finishing of Stereolithography Parts [PDF]
, 1993 Rapid Prototype polymer resin models produced by Stereolithography have, by the nature of the process, a relatively poor surface roughness, particularly on concave and convex surfaces.

Optimised Electro-Osmotic Flow in Rectangular Microchannels with Smoothed Corners
Journal of Physics: Conference Series, 2023 Abstract Electro-osmotic flows are a means of circulating polar fluids through microchannels without resorting to mechanical pumping. The lack of moving parts, of noise and the ease of integration in silicon chips make them an interesting option for microchip cooling and miniaturized total analysis systems.

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Advanced Engineering Materials, EarlyView.This study reports lightweight polyetherimide triply periodic minimal surfaces lattices coated with carbon nanotube‐reinforced epoxy that combine mechanical robustness with self‐sensing. The conformal coating enhances stiffness, strength and energy absorption while enabling reliable strain monitoring.

On the use of Higher Order and Irregularly Shaped Boundary Elements in Nearfield Acoustical Holography [PDF]
, 2004 Nearfield acoustical holography (NAH) is used to find the regions of acoustic activity on the surface of a sound radiating object. One of the most general NAH approaches is the inverse frequency response function (IFRF) technique, since it imposes no ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Advanced Engineering Materials, EarlyView.Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

On a selection principle for multivalued semiclassical flows [PDF]
, 2014 We study the semiclassical behaviour of solutions of a Schr ̈odinger equation with a scalar po- tential displaying a conical singularity. When a pure state interacts strongly with the singularity of the flow, there are several possible classical ...
