Figure 8
(a) A nominal-to-actual comparison of the investigated strut: the experimentally determined room diagonal of the lattice structure has an angle of 35.21° to the upper horizontal plate, while the nominal angle between strut and plate would be 35.27°. In (a) the struts are shown as shaded, and the positions of the gauge volumes used in neutron diffraction measurements are also displayed in red for the knot and in black for the strut. (b) A roughness analysis on a single strut by means of X-ray computed tomography for various build angles α. The strut of the lattice structure was built with α = 35.27°, indicated by a vertical line. (c) The measured lattice spacings for various positions along the strut. The black squares and red circles represent the measurements along direction `1' and the opposite direction (mirror).
