Materials Science in Additive Manufacturing Gyroid non-pneumatic tires through additive manufacturing

0.3 mm. Material properties were sourced from the 3DS 3. Results
Systems website for the Flex-BLK 20 resin, which has
a Young’s modulus of 1229 MPa and a Poisson’s ratio 3.1. Experimental testing and FEA validation

fixed flat surface in the simulation, while a displacement uniform thickness (Tire 1), another with sheet thickness
of 12 mm was applied to the hub in the downward ranging from 1.0 – 1.5 mm (Tire 2), and a third with sheet
direction, as illustrated in Figure 2. To achieve solution thickness ranging from 1.0 – 2.0 mm (Tire 3). Localized

convergence, a maximum of 1000 substeps was set, deformations were assessed at various displacement values
resulting in an incremental displacement of 0.012 mm (0 – 12 mm) for four different location sheet bands of
per substep for displacement of 12 mm. TPMS (L0 – L3) using DIC. Figures 3-5 illustrate the DIC
