Abstract. Additive manufacturing of lattice structures introduces geometrical imperfections that significantly affect their mechanical response. In this work, CT scans are used to reconstruct imperfect struts through a statistical description of their geometry. The reconstructed struts are employed to derive nonlinear tensile and bending responses, which are embedded into a reduced-order beam formulation in Abaqus. Results show that the simplified beam model captures the initial stiffness, yielding behavior, and orthotropic response of the CT-based models while significantly reducing the computational cost.
