Abstract: This Final Year Project (FYP) explores compression testing on kagome and Strut-Reinforced Kagome unit trusses to modelling and simulation of kagome truss structures. First, the models were created in SolidWorks, then 3D printed and physically tested. The truss structures are also modelled similarly and tested in Abaqus/CAE. Three-point bending is the selected testing procedure. This project is focused mainly on the compressive response of kagome unit and structures and the change in results with differing models. Data from the experiments in terms of force vs. displacement, peak strength, energy absorption and strain are analysed. The secondary foci are on three-point bending simulation in Abaqus/CAE and modelling in SolidWorks. The purpose of the simulation is to extract the behaviour and response of the models, for various model types with regards to the changes in dimensions. This information is extracted from the simulation results in the form of a force vs. displacement graph. With these information, the optimal design can be determined and possibly be used for future applications. The results of the experiments and simulations indicate that the SRK models generally perform better than the regular kagome models in almost all aspects considered. The experiments and simulations also show that models with more trusses directly underneath and above the contact pins and with thicker struts will be able to withstand more force before buckling and failure.
