| Résumé | In this study, the large deformation behaviour of 3D-printed structures with representative arrowhead shape topology is studied and compared with the corresponding responses of conventional hexagonal structures. Polymer and nylon specimens were manufactured by 3D printing. Quasi-static uniaxial tensile tests were conducted followed by finite element (FE) simulations. The deformation, tensile stress-strain curves and energy absorption of these architected composites are investigated. In addition, the standard mechanics homogenization is implemented through FE modelling to accurately predict the effective mechanical properties of arrowhead shape structures. A good agreement is observed between the results of detailed FE modelling and homogenization predictions. Subsequently, the effect of initial arrowhead angle is studied using FE analysis. |
