Figure 19: Stress-to-mass ratio versus displacement curves obtained
from three-point bending tests on various lattice structures.
The graphs, illustrated in Figure 18 and 19, show different
stress/mass ratios at different vertical displacements on the
rectangular beam with different lattices; some were strut-based
