Recent advances in science and engineering allowed obtaining the novel materials with unusual mechanical properties. In many cases, these properties are mainly determined by the microstructure of the materials on small scales (micro- and nano-) rather than by the chemical and physical properties. Usually, the microstructure is obtained naturally such as in the case of nanomaterials and specifically 2D-materials. However, recent progress in manufacturing techniques inspired the engineers to construct the artificial materials referred to as ‘metamaterials’. In his Musltiscale Mechanics of Solids (MSMS) lab Dr. Berinskii and his team investigate a connection between the microstructure and macroscopic mechanical behavior by means of analytical and computational analysis. Their aim is to explain existing unusual mechanical properties and predicting new outstanding features to be used in engineering applications.
