Abstract: 
The Research Laboratory on the Mechanics of smart Materials and Structures (MS2 Laboratory) focuses on understanding the mechanisms underlying the experimentally or numerically observed phenomena of smart materials and intelligent structures, so as to enrich the knowledge for the development of advanced functional devices, machines, and robots. Particular attention is paid to the multi-field coupling behaviors of a variety of high-performance materials (e.g. piezoelectric materials, multiferroic composites, quasicrystals, piezoelectric semiconductors, and dielectric elastomers) and their effects on the structural responses. Free vibration, wave propagation, and instability of structures made of these smart materials are among the most important topics in the laboratory. Although analytical methods are concentrated upon, both experimental and numerical approaches are also widely explored for the research tasks that are carried out.
