P. Ladeveze et J. Simmonds, NEW CONCEPTS FOR LINEAR BEAM THEORY WITH ARBITRARY GEOMETRY AND LOADING, European journal of mechanics. A, Solids, 17(3), 1998, pp. 377-402
A new approach is introduced for the analysis and calculation of strai
ght prismatic beams of piecewise constant cross-section under arbitrar
y loads. This theory can be called ''exact'' because it determines exa
ct static and kinematic generalized quantities. Moreover, contrary to
classical theories, it is not limited to high-aspect ratio (i.e. relat
ively slender) beams. (C) Elsevier, Paris.
