Simulation of the Compression Testing of Additively Manufactured Lattice Structures Using Inputs from Microcomputed Tomography

Table 3

Mechanical properties of lattices for experimental (Exp) and numerical (Num) results and as-design model for numerical results only as an as-designed model cannot be investigated through experimental methods [25].
