Determination of the shape of a beam obtained by fused deposition material with general loads

Abstract

Abstract In this paper, we develop a general procedure for the obtaining of the shape of a beam obtained by FDM and having arbitrary loads. The beam is subjected to bending loads and because of its small elasticity modulus the approximate theory presented in the strength of materials cannot be applied. We used the general equation for the deformation of the beam resulting non-linear equations for the bending moment, the shear force, the rotation, the elongation and the deflection. These relations are solved by numerical methods. An example will highlight the theory.
