This classic account describes the known exact solutions of problems of heat flow, with detailed discussion of all the most important boundary value problems.

IN this monograph I have attempted to set out, in as elemen- tary a form as possible, the basic mathematics of the theories of elasticity, plasticity, viscosity, and rheology, together with a discussion of the properties of the materials involved and the way in which they are idealized to form a basis for the mathe- matical theory. There are many mathematical text-books on these subjects, but they are largely devoted to methods for the solution of special problems, and, while the present book may be regarded as an introduction to these, it is also in- tended for the large class of readers...
