Finite Element Analysis of Hexagonal Tube Structures Under Axial Loading

Elastic-perfectly plastic material is assumed in the model using the non-linear facilities of the finite element code ABAQUS in hexagonal tube structures. A four-noded quadrilateral (S4R) of shell elements in used in the analysis. The load-displacement curves are examined and compared with experiment. It has been found both experimentally and throughout finite element method that the form of the two load-displacement curves are approximately the same throughout the compression. The FE mean load is in close agreement with experiment. However, the FE plastic fold length is found to have overestimated the experimental result by 10%. The strain history is also examined and it is found that the form of the predicted curves are in agreement with the experiments at locations away from the end.
