NettetEuler-Bernoulli beam theory. Part of the Solid Mechanics and Its Applications book series (SMIA,volume 163) A beam is defined as a structure having one of its dimensions much larger than the other two. The axis of the beam is defined along that longer dimension, and a crosssection normal to this axis is assumed to smoothly vary along … Nettet1. mai 1998 · The classical first-order beam theory, the modified first-order beam theory and a higher-order beam theory lead to the FOSB, the MFOSB and the HOSB models respectively.

http://www-personal.umich.edu/~awtar/PHD/Thesis/chapter3_final.pdf NettetElastica theory is an example of bifurcation theory. For most boundary conditions several solutions exist simultaneously. When small deflections of a structure are to be analyzed, elastica theory is not required and an approximate solution may be found using the simpler linear elasticity theory or (for 1-dimensional components) beam theory.

P. Seide [54] investigated the large deformation of an extensional simply supported beam loaded by a bending moment at its end, and he found that reasonable results are obtained by the linear theory for relatively large rotations of the loaded end.

In static Timoshenko beam theory without axial effects, the displacements of the beam are assumed to be given by where are the coordinates of a point in the beam, are the components of the displacement vector in the three coordinate directions, is the angle of rotation of the normal to the mid-surface of the beam, and is the displacement of the mid …
