Hard turning and grinding are competitive processes in many cases for manufacturing various mechanical products. Product performance is highly dependent on the process induced residual stresses. However, there exist some inconsistence regarding the true residual stress profiles generated by hard turning and grinding with and without the presence of a ...

For the purpose of investigating the effect of cutting edge truncation on ground surface morphology, several kinds of hard and brittle materials used for optical devices, borosilicate glass, glass quartz, crystal quartz and sapphire, are plunge ground with a SD600 metal-bonded grinding wheel, the cutting edges of which are truncated so as to be aligned

Over the last several years a 2-D finite difference acoustic propagation program for finite amplitude interactions has been developed at the University of Illinois and USA-CERL. In this presentation the addition of the numerical coupling of the air to the hard surface and porous media models of the ground will be described.

IEEE Transactions on Antennas and Propagation, 2005
A periodic ground plane may be built to either stop the propagation of wave or support a quasi transverse electromagnetic wave along the surface. The former is called a soft surface, and the latter is a hard surface. However, a soft or a hard surface can only be realized in certain frequency and wavenumber regions; therefore, it is important to ...

Abstract The characteristics of residual stress (RS) profiles and their effects on rolling contact fatigue life for precision turned and ground surfaces with a white layer (WL) are very controversial. This study has shown that: (a) Hard turning with a fresh tool generates a “hook” shaped RS profile characterized by surface compressive RS and ...

IEE Proceedings - Microwaves, Antennas and Propagation, 1995
Simple and closed form expressions for plane wave reflection coefficients of a dielectric slab loaded with a periodic array of strips over a ground plane are presented for use in antenna applications. In the analysis, a set of integral equations for the fields between the strips and dielectric slab are derived from the three-dimensional boundary value ...

This article presents the applicability of Automatic Geodetic Monitoring (AGM) for measuring surface displacements in an area affected by deep mining. The accuracy of the interpreted data was investigated by comparing the height differences determined from the AGM results with the reference height differences obtained by precise levelling.
