| General note | Additive Manufacturing (AM) techniques, such as Selective Laser Melting (SLM),<br/>have gained significant attention in recent years by providing design freedom to engineers to<br/>design and fabricate complex cellular structures with tailored mechanical properties. To balance<br/>the strength and weight, 3D lightweight metallic Body-Centered Cubic (BCC) lattice sandwiches<br/>were fabricated by selective laser melting with titanium alloy (Ti6AL4V). This study investigates<br/>the mechanical responses under compression and three-point bending tests experimentally and<br/>numerically. The experimentally measured strengths are very close to the numerical predictions,<br/>demonstrating excellent mechanical properties. The numerical modelling may represent the stressstrain load-deflection curves, and the failure mode is the strut buckling initiated from the plastic<br/>hinges with high stress levels. This paper also explores the mechanical properties of functionally<br/>graded density BCC lattice structures, which results in different performances in mechanical<br/>behavior compared to uniform graded density BCC lattice structures. Due to the gradient lattice<br/>structure, the average bending load capacity significantly increases from 6000.0 N to 16000.0 N.<br/>We indicate that the BCC lattice structure only exhibits a dual failure model comprising buckling<br/>and fracture, in contrast to other lattice structures that often offer sole buckling or fracture failure.<br/>The buckling failure of the struts near the bottom face sheets always arises first and is followed by<br/>the subsequent fracture. The BCC lattice sandwiches offer an opportunity to effectively balance<br/>strength and weight as they present lower density than engineering alloys and higher strength than<br/>honeycombs, foams and pyramid lattice sandwiches. |
