Dislocations in wave trains

When an ultrasonic pulse, containing, say, ten quasi-sinusoidal oscillations, is reflected in air from a rough surface, it is observed experimentally that the scattered wave tra...

Multiplication Processes for Slow Moving Dislocations

Reducing waste: repair, recondition, remanufacture or recycle?

Abstract Between 1980 and 1997, municipal waste in OECD countries increased by around 40%. This paper outlines the very real negative effects of this increase and then introduce...

The Mechanical Properties of Metals

A description is given of edge and screw dislocations in a close-packed cubic lattice, which leads up to an account of the theory of Frank and Read of the origin of slip bands. ...

The<i>T</i>matrix, the<i>K</i>matrix, d bands and<i>l</i>-dependent pseudo-potentials in the theory of metals

The `Green's function' method for the calculation of electronic band structure is investigated. The general T-matrix theory of Beeby and Edwards is used to transform the formula...
