Static analysis of a Bickford beam by means of the DQEM
No full textIn this paper the recently proposed differential quadrature element method is employed in order to solve the equilibrium equations of a
higher-order beam. A simple five-node element is introduced, in which the vertical displacement is approximated by a sixth-order
polynomial, whereas the rotation is consistently approximated by a fourth-order polynomial, and the resulting weighting coefficient
matrix is given. Moreover, a general procedure is outlined, for an N-node element, in which vertical displacements and rotations are
given by polynomials of order N þ 1 and N 1, respectively. Numerical examples are aimed both at checking the convergence of the results for increasing values of the nodes, and at comparing the used cubic beam theory with the simpler, linear, Timoshenko theory

No full textIn this paper, the well-known Mohr analogy is applied to the computation of displacements and rotations of carbon nanotubes, and some simple formula is derived which allows the direct generalization of the Mohr theory to the nonlocal Euler–Bernoulli and Timoshenko beam theories. Finally, some examples show the effectiveness and simplicity of the proposed approach
