The linearized theory of elasticity has long played an important role in engineering analysis. From the cast-iron and steel truss bridges of the eighteenth century to the international Space station, engineers have used the linearized theory of elasticity to help guide them in making design decisions effecting the strength, stiffness, weight, and cost of structures and components.
The Linearized Theory of Elasticity is a modern treatment of the linearized theory of elasticity, presented as a specialization of the general theory of continuum mechanics. It includes a comprehensive introduction to tensor analysis, a rigorous development of the governing field equations with an emphasis on recognizing the assumptions and approximations inherent in the linearized theory, specification of boundary conditions, and a survey of solution methods for important classes of problems. It covers two- and three-dimensional problems, torsion of noncircular cylinders, variational methods, and complex variable methods.
The mathematical framework behind the theory is developed in detail, with the assumptions behind the eventual linearization made clear, so that the reader will be adequately prepared for further studies in continuum mechanics, nonlinear elasticity, inelasticity, fracture mechanics, and/or finite elements. Prior to linearization, configurations and general (finite deformation) measures of strain and stress are discussed. A modern treatment of the theory of tensors and tensor calculus is used. General curvilinear coordinates are described in an appendix.
An extensive treatment of important solutions and solution methods, including the use of potentials, variational methods, and complex variable methods, follows the development of the linearized theory. Special topics include antiplane strain, plane strain/stress, torsion of noncircular cylinders, and energy minimization principles. Solutions for dislocations, inclusions, and crack-tip stress fields are discussed. Development of the skills and physical insight necessary for solving problems is emphasized. In presenting solutions to problems, attention is focused on the line of reasoning behind the solution.
