Beam theories are exploited worldwide to analyze civil, mechanical,
automotive, and aerospace structures. Many beam approaches have been
proposed during the last centuries by eminent scientists such as Euler,
Bernoulli, Navier, Timoshenko, Vlasov, etc. Most of these models are
problem dependent: they provide reliable results for a given problem,
for instance a given section and cannot be applied to a different one.
"Beam
Structures: Classical and Advanced Theories" proposes a new original
unified approach to beam theory that includes practically all classical
and advanced models for beams and which has become established and
recognised globally as the most important contribution to the field in
the last quarter of a century. The Carrera Unified Formulation
(CUF) has hierarchical properties, that is, the error can be reduced by
increasing the number of the unknown variables. This formulation is
extremely suitable for computer implementations and can deal with most
typical engineering challenges. It overcomes the problem of classical
formulae that require different formulas for tension, bending, shear and
torsion; it can be applied to any beam geometries and loading
conditions, reaching a high level of accuracy with low computational
cost, and can tackle problems that in most cases are solved by employing
plate/shell and 3D formulations.
Key features: compares
classical and modern approaches to beam theory, including classical
well-known results related to Euler-Bernoulli and Timoshenko beam
theories pays particular attention to typical applications related to
bridge structures, aircraft wings, helicopters and propeller blades
provides a number of numerical examples including typical Aerospace and
Civil Engineering problems proposes many benchmark assessments to help
the reader implement the CUF if they wish to do so accompanied by a
companion website hosting dedicated software MUL2 that is used to obtain
the numerical solutions in the book, allowing the reader to reproduce
the examples given in the book as well as to solve other problems of
their own www.mul2.com. Researchers of continuum mechanics of
solids and structures and structural analysts in industry will find this
book extremely insightful. It will also be of great interest to
graduate and postgraduate students of mechanical, civil and aerospace
engineering.
