✦ Synopsis
Superposition and the role of Duhamel's theorem in obtaining solutions to certain nonhomogeneous problems are considered next. Chapter 5, "Complex Combination", is devoted to obtaining the sustained, periodic response of a system to a periodic disturbance; a step-by-step procedure to accomplish this objective is presented on p. 168.
An introduction to "Laplace Transforms" is presented to acquaint the reader with this approach to a degree that he is able to at least solve elementary problems. (The author might well consider including a more complete discussion of integral transform techniques in future editions.) "Normalization" is the topic of Chap. 7. A lucid presentation is given, centering upon the utility of dimensional methods for (i) easing the solution to heat-transfer problems and (ii) for interpreting physically the solutions achieved. Also, the effectiveness of normalization in making engineering approximations is reviewed in Section 7.2.
Chapters 8 and 9 are devoted to a discussion of numerical methods that can be performed on the computer. The finite-difference method is discussed. The importance of thermal-stress calculations provides the motivation for considering the finite-element method. (Some experience with variational calculus is desirable for the finite-element discussion.)
The author includes a discussion of many "advanced" problems in each of these two chapters-namely, problems involving variable geometry, variable thermal properties and radiation boundary conditions.
