Description
Summary:Lattice structures have a number of applications in aerospace, automobile and defense industries because of their high specific strength and stiffness. Additive manufacturing technology has allowed realizing various regular morphological cellularic structures with a combination of materials. In this study, the compressive performance of modified Kagome unit cell namely strut reinforced Kagome (SRK) of acrylonitrile butadiene styrene (ABS) ABSplus™ fabricated by fused deposition modeling (FDM) is investigated. The effect of the change in the geometric parameters such as diameter and height on the compressive properties is studied. The failure modes under uniaxial compression are simulated with the finite element simulations and the calculated effective modulus are compared with the experimental measurements.
