Numerical Analysis On Static And Dynamic Behavior Of Additively Manufactured BCC Lattice Structures

This research aims to investigate the effect of the strut diameter of lattice structures on their vibration characteristic numerically. The finite element analysis (FEA) method was validated beforehand in experimental work with lattice structure fabricated using fused deposition modeling (FDM) addit...
