✦ Synopsis

The necessary and sufficient conditions which must be satisfied by a physical process (e.g., the diffusion of heat through a body) in order that its mechanical effects can be represented by mechanical dislocations are derived for anisotropic media. It has been found that the only kind of physical processes which can be represented by mechanical dislocations are those which are steady-state processes with respect to time. Further, it has been found that in order for a steady-state physical process to be represented by mechanical dislocations in an anisotropic body, certain relationships between the coe~cients which govern the physical process must be satisfied. Several examples of materials and processes for which the required relationships are satisfied have been presented.
