Finite element analysis of Miura origami column under uniaxial compressive load

Abstract

This paper presents the finite element analysis (FEA) of 3D printed Miura origami column under uniaxial compressive loading condition. The finite element model (FEM) was developed under elastic-perfectly plastic material model. Investigation on the yield strength and compressive modulus with two varied parameters, i.e. angle and thickness of the Miura origami column was conducted. Abaqus 6.14 software was used to conduct the simulation of compression test. The simulation result is then compared with and examined to the referred experimental data. From the simulation, it was revealed that the results from FEA of Miura-ori column with θ = 90° and t = 2 mm showed good agreement with the referred experimental data. However, FEA results mostly overestimates the mechanical properties. This discrepancy could be due to the existence of imperfections and anisotropic material of 3D printed structures.
