Stress and strain analysis of rotors subjected to surface and body
loads, as well as to thermal loads deriving from temperature
variation along the radius, constitutes a classic subject of
machine design. Nevertheless attention is limited to rotor profiles
for which governing equations are solvable in closed form.
Furthermore very few actual engineering issues may relate to
structures for which stress and strain analysis in the linear
elastic field and, even more, under non-linear conditions (i.e.
plastic or viscoelastic conditions) produces equations to be solved
in closed form. Moreover, when a product is still in its design
stage, an analytical formulation with closed-form solution is of
course simpler and more versatile than numerical methods, and it
allows to quickly define a general configuration, which may then be
fine-tuned using such numerical methods.
In this view, all subjects are based on analytical-methodological
approach, and some new solutions in closed form are presented. The
analytical formulation of problems is always carried out
considering actual engineering applications. Moreover, in order to
make the use of analytical models even more friendly at the product
design stage, a function is introduced whereby it is possible to
define a fourfold infinity of disk profiles, solid or annular,
concave or convex, converging or diverging. Such subjects, even
derived from scientific authors contributions, are always aimed at
designing rotors at the concept stage, i.e. in what precedes
detailed design. Among the many contributions, a special mention is
due for the following: linear elastic analysis of conical disks and
disks with variable profile along its radius according to a power
of a linear function, also subjected to thermal load and with
variable density; analysis of a variable-profile disk subjected to
centrifugal load beyond the material's yield point, introducing the
completely general law expressed by a an n-grade polynomial; linear
elastic analysis of hyperbolic disk, subjected to thermal load
along its radius; linear elastic analysis of a variable-thickness
disk according to a power of a linear function, subjected to
angular acceleration; etc."
