“…The exact solution to Equation ( 2) can be given in elliptic functions known as the analytical solution of an elastica [26,27], as has been shown in earlier solutions [43,45,46]. The vibrations of such a beam has been studied with the EGM also in a similar procedure [4].…”

“…The nonlinear beam theory with the options for both physical and kinematic linearities is certainly the choice for large deformation, but the nonlinear equations have to be solved with approximate methods, as shown in a recent study of the flexure of a cantilever beam under a point load [16,[20][21][22][23][24]. It is highly nonlinear differential equation for the classical problem of an elastica, and the accurate solutions can be given in elliptic functions through extensive studies in history [1][2][3][25][26][27]. To obtain practical solutions to nonlinear differential equations, many approximate techniques have been tried for improved solutions and simpler procedures including the finite-element method and alternative formulation [16,[28][29][30][31][32][33][34][35][36][37][38][39].…”

“…An interesting example of nonlinear analytical approach for a cantilever beam by means of elliptic functions is given in Mattiasson, 1 where a dead load is applied at beam's tip and the neutral axis displacement is described in terms of dimensionless parameters. In Iandiorio and Salvin, 2 a closed form solution is obtained using a methodology that uses a new hypergeometric function of two variables and is applied for isotropic beams subjected to concentrated loads, where integration of elliptic functions is avoided. Tasora et al 3 present a geometrically exact formulation for solving three‐dimensional beams based on shear‐flexible Cosserat rod theory, where the beam is described by its centerline and its displacement and section rotation are parameterized by means of spline interpolation of quaternions.…”

“…Besides, (c) the rod axis is supposed to be inextensible. In light of these hypotheses, several past [34][35][36] as well as current [37][38][39][40] investigations can be found in literature dealing with different structural problems. In this paper, the additional assumption that the Young's modulus varies along the rod axis, accounting for the nonhomogeneity of the cantilever, is considered.…”
