The ability to design, manipulate, characterize and fabricate materials at the nanoscale is a central goal of the sessions of this conference. Properties of nanomaterials such as reactivity, melting point, fluorescence, mechanical strength, and electrical conductivity can be altered at the nanoscale, making it difficult to predict how these materials interact with humans and the environment. Advanced computational simulations to theoretically explain the specific physical and chemical properties of the nanomaterials and to predict new ones.

This session invites theoretical and experimental contributions dealing with all aspects of nonlinear dynamical systems, as well as structural control and monitoring, in the area of mechanical, structural and civil engineering.

Mechanical systems with nonlinearities represent a large group of dynamical systems. Nonlinearity can be introduced in a variety of ways: by geometry; by characteristics of springs and dampers; by friction or impacts, etc. The dynamics of such systems is complex and can lead to unexpected behavior, and the detailed knowledge about stability and coexistence of solutions is the crucial issue. In many applications the usefulness of nonlinear systems exceeds the linear ones, which allows them to be used for significantly wider purposes. We welcome all submission focused on nonlinear dynamical systems and their applications in mechanical and structural systems.

We invite also contributions on mechanical and structural control systems, including active, adaptive, distributed and semi-active control strategies, as well as related actuators. Such systems can be designed to employ smart strategies of structural adaptation to external excitations and vibration patterns. The adaptation might be implemented through a number of diverse physical mechanisms and smart materials (magnetorheological fluids, tuned inerter dampers, piezoelectric actuators, bistable valves, etc. ). Various control objectives are possible, such as dissipation of vibration or impact energy, protection of specific substructures, minimization of displacements and accelerations, etc. The nonlinearity or bilinearity of the involved control encourages nonstandard optimization approaches.

Finally, we encourage contributions in the area of structural health monitoring. This field involves local nondestructive testing, global monitoring systems, and their applications for damage detection, localization, and quantification. The topics of interest include the related problems of indirect input estimation and tracking, lifetime prediction, optimization of sensor systems, as well as sensing technologies, and reports on practical applications.

The theories and applications of plasticity remain in the focus of interest in mechanics of materials and structures. This includes the microstructural background of plasticity representation of anisotropy and unstable material response coupling with other constitutive theories. Alternative mathematical frameworks and algorithmic aspects of plasticity are also considered. Moreover new plastic models are developed for multiscale phenomena and multi physics research in particular for thermoplasticity.

Within the damage and fracture mechanics part of the session, research communications are sought on the influence of defects at different scales on the mechanical response of materials and structural components. Contributions which provide a better understanding of the mechanisms of crack nucleation and growth along with their impact on engineering applications are welcome. Macroscale micromechanical, multiscale and atomistic models of damage and fracture fall within the scope of this session.
