Implication

Simulation and mechanical testing demonstrate predictable yield strength in 3D-printed gyroid infills, suggesting streamlined design workflows for topology optimization.

Key Points

To evaluate and predict the effective compressive and shear yield strengths of additively manufactured gyroid infill structures across varying relative densities.
Discretized a representative volume element of the gyroid infill with solid elements using an elastic–plastic constitutive finite element model under periodic boundary conditions.
Simulated compressive and shear loading across varying infill densities to obtain effective yield strengths.
Manufactured prototype specimens using polymer extrusion-based 3D printing to experimentally validate the numerical models.
Numerically calculated compressive and shear yield strengths matched experimental measurements across the tested gyroid infill prototypes.
A semi-empirical relationship was established to directly compute effective yield strength as a function of relative infill density for structural optimization.
