Our main interest in this work is lattice-type structures that are characterized by two properties: periodicity and small thickness of the material. We have several types of such structures that consist of identical cells periodically distributed in all directions, reticulated structures (see Figure 2.1); or in two directions, gridworks (see Figure 2.2); or in only one direction, tall structures (see Figure 2.3). If the material is concentrated along layers, then we speak about honeycomb structures (Figure 2.4), and if along bars, then reinforced structures (see Figure 2.5).
