This volume addresses the stress and strain state in machine components and mechanical structures featuring axial symmetry in the broad sense, i.e., referring not only to the structure's geometrical shape (this is the so-called geometrical cylindrical axisymmetry, and the generic cross-section is thus circular or annular), but also to the distribution of surface forces, the thermal loads acting on the structure, the boundary conditions, the material's elastic properties, and if necessary the body forces. The textbook also describes methods for evaluating the strength of such structural components and thus ensure that they are correctly designed and meet the criteria specified for compliance checks in national and international standards. Here, analysis is restricted to structures consisting of homogeneous and isotropic material: for structures consisting of plastic or composite materials, the reader is referred to specialized texts. The structures considered herein include, for example, pressure vessels, nuclear vessels, reactor liners, solid fuel elements, control rods, the reactors used in the chemical and petrochemical industries, the tubing and, more generally, the piping in manufacturing plants, the casings, tubing and drill pipes used in oil and gas fields, the piping in offshore drilling operations, the pipelines that carry oil and natural gas, heat exchanger tubes, the shrink-fit shaft/hub assemblies employed in the mechanical industry and the components of many other machines used in sectors spanning the gamut from aerospace to domestic appliances. Special topics that will be addressed in this area include composite material vessels, elastomer tubes, sleeves, box couplings, the petrochemical industry's storage tanks, coining dies, multilayer tanks and their optimization, the loosening of a shrink-fit shaft/hub assembly as a result of centrifugal load, limit analysis design, autofrettage, or the creation of a residual stress in an internally pressurized cylinder when the internal pressure is increased from the value causing initial yielding to the value causing yielding of the entire cross section, and the thermal stresses in long cylindrical bodies.
