Nonlinear Vibration Analysis of Smart Materials

Dear Colleagues,

Smart materials, also known as intelligent or responsive materials, exhibit changes in one or more properties in response to external stimuli such as temperature, pressure, electric or magnetic fields, light, pH, or chemical compounds. For engineers and scientists to design more efficient and effective smart systems, a deeper understanding of the nonlinear behavior of these materials is necessary. A critical area of study in materials science and engineering, particularly, is the nonlinear vibration analysis of smart materials. Namely, it is a multidisciplinary field requiring knowledge of materials science, mechanics, and numerical methods.

The nonlinear vibrations of smart materials, unlike linear vibrations, which assume a direct proportionality between the response and the excitation, involve more complex relationships, where the response may not be directly proportional to the aforementioned various types of excitation. In this issue, the nonlinear vibration of the piezoelectrics, shape memory alloys, magnetostrictive materials, and also of new metamaterials will be considered.

Research topics:

1. Complex Material Behavior: The characterization of the nonlinear properties of smart materials under different operating conditions;
2. Modeling and Simulation: Developing accurate models that can predict the nonlinear vibration behavior of smart materials under various loading conditions;
3. Solving procedures for nonlinear vibrations—Analytic and Numeric Methods: The development of new problem-solving procedures for strong nonlinear vibration equations that couple various effects (electrical, chemical, thermal, etc., with mechanical effects);
4. Control of vibration: The effective integration of smart materials into practical systems, considering factors like control systems, material science, and mechanical engineering;
5. Advanced smart materials: Research into new smart materials with enhanced properties and capabilities and better performance for specific applications.

Understanding the nonlinear vibration characteristics of these materials is essential for their application in sensors, actuators, and other smart systems.
