Basic Guidelines for Plastic Conversion of Metal Axial Flow Fans

This paper compares the performance of two alternative HVAC fan designs: a five-blade injection molded thermoplastic design, against the more traditional three-blade stamped metal version. The study was conducted using computational fluid dynamics techniques, along with finite element structural analysis, in which we attempted to optimize the air movement characteristics of the fan, as well as ...

A Metal-Acrylic Bar for Splinting Implant Impression Copings

Precise transfer of three-dimensional position of dental implants from oral cavity to the cast needs special considerations in impression making. It has been suggested to splint the copings by bars or acrylic resin material before making impression. Some problems regarding to polymerization shrinkage of acrylic resin have been reported. In this study, we describe a metalacrylic bar tha...

A local constitutive model with anisotropy for ratcheting under 2D axial-symmetric isobaric deformation

A local constitutive model for anisotropic granular materials is introduced and applied to isobaric (homogeneous) axial-symmetric deformation. The simplified model (in the coordinate system of the bi-axial box) involves only scalar values for hydrostatic and shear stresses, for the volumetric and shear strains as well as for the new ingredient, the anisotropy modulus. The non-linear constitutiv...

The Effect of Normal Anisotropy on Thin-Walled Tube Bending

Thin-walled tube bending has common applications in the automobile and aerospace industries. The rotary-draw-bending method is a complex physical process with multi-factor interactive effects and is one of the advanced tube forming processes with high efficiency, high forming precision, low consumption and good flexibility for bending angle changes. However, it may cause a wrinkling phenomenon,...

The Bar Involution for Quantum Symmetric Pairs

We construct a bar involution for quantum symmetric pair coideal subalgebras Bc,s corresponding to involutive automorphisms of the second kind of symmetrizable Kac-Moody algebras. To this end we give unified presentations of these algebras in terms of generators and relations, extending previous results by G. Letzter and the second-named author. We specify precisely the set of parameters c for ...
