Absorption (A) is a process that involves energy transformation. The energy levels of a substance determine the wavelengths of light that can be absorbed. It is a molecular phenomenon dependent on the chemical identity and structure of the substance (not on the size of the molecules or clusters) and involves electronic transitions vibrations

The areas under the load-deflection curves in Figure 1.3.5 characterize the energy absorption. The capability of a quasi-brittle structure to absorb energy decreases in relative terms as the structure size increases. The size effect on energy absorption capability is important for blast loads and impact.
