Flexural Behavior of Bidirectionally Graded Lattice

open access: yesAdvanced Engineering Materials, EarlyView., 2023
An experimental study of the bending behavior of bidirectional body‐centered cubic lattice beams is conducted in comparison to uniform and unidirectional counterparts of electron beam melted SS 316 L. Experimental results are used to develop and validate a finite element model which is subsequently used to conduct parametric studies to assess the ...
