Introduction and Scope During recent years, remarkable progress has been made in the development of new materials. Advanced structured materials, including smart and nano materials, have opened up new engineering possibilities because of their specific properties (chemical, mechanical, and physical) that are not found in nature, and can be significantly changed by a user in a controlled manner to make them appropriate for certain applications. Due to their unique properties, smart and nano materials have been of interest in countless areas of technical application, in various systems and structures, including intelligent and adaptive sensing or actuation, as well as active control. An understanding of the relationships between their structures and properties is of crucial importance for the practical utilization of these materials. Over the past several years, a series of approaches for progress in structural control and healthy monitoring have left paramount impacts on our everyday lives. This has shaped the framework of many engineering fields. Given the current state of quantitative and principled methodologies, nowadays, it is possible to rapidly and consistently evaluate the structural safety of mechanical systems, industrial machines, and modern concrete buildings, etc., to test their capability for serving their intended purpose. However, un- solved, problematic, and new challenges exist. Unmolded nonlinearities, ineffective sensor placement, and the effects of confounding influences due to operational and environmental variabilities still harm the effectiveness of the state of structural control and healthy moni- toring systems. A typical integrating structural control and health monitoring system is shown in Figure 1. The aim of this Special Issue is to gain new, unique knowledge about the relationships between the structures and physico-mechanical and chemical properties of new materials, including finding ways to structure the control and development of new methods for struc- tural healthy monitoring. Another goal is to gather the main contributions of academics and practitioners in mechanical, aerospace, and civil engineering to provide a common ground for improvements to these approaches to structural control and healthy monitoring, by using the unique properties of smart and nano materials. Studies concerning sensor technologies, vibration-based techniques, artificial-intelligence-based methods, and related fields are all welcome, in both numerical and experimental form.
