The textbook "Wave Dynamics and Composite Mechanics for Microstructured Materials and Metamaterials" offers a comprehensive analysis of the technological challenges and design aspects in the field of modern metamaterials. The authors develop models that investigate the mechanical, electromechanical, and acoustic behavior of these materials, focusing on interactions at the micro level. The created models are validated through empirical observations at a phenomenological level. The book presents solutions based on fundamental methods and models, including wave propagation theory and nonlinear theories, to analyze media with micro and nanostructures. Topics covered include models with cracks and defects, as well as the integration of piezoelectric elements and coupled physical-mechanical fields. The results of the investigations demonstrate that analytical, numerical, and experimental methods can be employed to assess the qualitative and quantitative properties of these materials.
