“…If the thickness of the cantilever column is much less than its length, the theory of elastica [21,22] adequately describes the large, nonlinear displacements due to the loads. In this theory, deformations are due mainly to bending moments and it is usual to begin with the classical Bernoulli-Euler beam theory expressed by the nonlinear differential equation that relates deflection to load [25]. The following assumptions are inherent in this theory: (a) the column is linearly elastic, (b) the neutral axis for post-buckling of the column is inextensible, and (c) the effects of Poisson's ratio and transverse shear deformations are negligible [27].…”

“…They are usually designed to accept large displacements but deformations are kept within the elastic regime. One of the examples illustrating the buckling phenomenon is the classical problem of the elastica [22][23][24][25][26][27][28][29][30]. Thin cantilever columns, being flexible, exhibit large deflections and slopes.…”

“…Para o caso de se assumir rotações iguais em ambas as extremidades da viga, oposta à extremidade da coluna em análise, TIMOSHENKO (1961) sugere: Para obter o valor de S subtrai-se desse total a rigidez ao deslocamento lateral da coluna subtraída, por sua vez, de C P/h.…”
