THE MOTION OF A DISLOCATED CONTINUUM

Abstract

A theory describing the mechanical properties of metals must include the methods of physics, of metallurgy and of applied mechanics. This unification is the primary object of the present work: starting from th p ysicists' analysis of a metal in terms of a lattice cell amenable to quantum mechanics, it is shown how th continuum geom try of mod rn islocation theory can be developed. Some disagreement with existing formulations is found, and a greater degree of exactn s is maintained for the sake of generality. An attempt is made to derive equations for the motion of a dislocated lattice (which is the real purpose of dislocation theory) by studying the motions of th geometry mentioned. Considerably more work on his theory is required to understand and apply the equations which have been developed. Two lines of study in associated fields which would prove valuable are t e physics of the transition in atomic states responsible for dislocation motion and an experimental assessment of lattice configurations under typical conditions.
