The tensile stress-strain response was determined for both types of materials.
Two types of materials were studied, i.e. cast and prepared by LPBF.
The microstructure of LPBF material is composed of cells / melting pools typical for materials prepared by this type of AM (Fig. 1c).

K pairs of PZT patches with the same geometric and material characteristics are bonded symmetrically to the top surface and bottom surface of the panel a and panel b, respectively.
If it is assumed that the thickness of the PZT patches is negligible compared with that of the panels, the density of two materials is approximately the same, and the size of the actuators is small compared with the wavelengths considered.

Moreover, in order to achieve the objective of the above-mentioned lightness, a large use of materials like steel, plastic and similar light materials has been made, thus resulting in a very large diffusion of several types of steel structures, including or consisting of pin-jointed systems (Figs 1-2).
