Solución Estática Exacta para Estructuras Prismáticas de Láminas Planas Plegadas

Abstract

An alternative approach foe the analysis of folded plate
structures is presented. As in the Finite Strip method, Fourier expansions are used in the axial direction in order to simplify the equations, but then exact solutions are used in the transverse direction. In this way it is not necessary to diacretize the structure. Only the displacements at the intersection of the plates hold as deqrees of freedom. Convergence is reached by increasing
the number of longitudinal modes.
A complete formulation of the problem and solution procedure is presented. The base functions, stiffness matrices and load vectors are explicitly given in the apendices.
