Upper Bound Analysis of Tube Extrusion Process Through Rotating Conical Dies with Large Mandrel Radius

In this paper, an upper bound approach is used to analyze the tube extrusion process through rotating conical dies with large mandrel radius. The material under deformation in the die and inside the container is divided to four deformation zones. A velocity field for each deformation zone is developed to evaluate the internal powers and the powers dissipated on all frictional and velocity disco...

Application of interference methods for determination of curvature radius in metal–oxide–semiconductor (MOS) structures

The paper deals with the measurement of the radius of curvature of silicon wafer surface. The aim of these measurements was to determine stresses generated during oxidation of silicon wafers. A greater molar volume of SiO2 layer in relation to the substrate material causes changes in the shape of oxidized surface, which results in stresses in both silicon dioxide layer and silicon. These change...

Method for determination of root curvature radius using cone-beam computed tomography images.

This article describes and discusses a method to determine root curvature radius by using cone-beam computed tomography (CBCT). The severity of root canal curvature is essential to select instrument and instrumentation technique. The diagnosis and planning of root canal treatment have traditionally been made based on periapical radiography. However, the higher accuracy of CBCT images to identif...

New Method of Determination for Pressure and Shear Frictions in the Ring Rolling Process as Analytical Function

Ring rolling is one of the most significant methods for producing rings with highly precise dimensions and superior qualities such as high strength uniformity, all accomplished without wasting any materials. In this article, we have achieved analytical formulas for calculating the pressure and shear friction over the contact arcs between the rollers and ring in the ring rolling process for the ...
