What are the applications of nanomechanics modeling and simulation in cyclic loading?

2 Nanocoatings and thin films

Nanocoatings and thin films are layers of materials with nanometer thickness that are applied to the surface of substrates to enhance their functionality and durability. They are used in various fields, such as optics, electronics, biomedicine, corrosion protection, and tribology. However, they are also exposed to cyclic loading in many situations, such as thermal cycling, mechanical loading, and environmental stress. Nanomechanics modeling and simulation can help evaluate the adhesion, delamination, cracking, and wear behavior of nanocoatings and thin films under cyclic loading, and optimize their composition, structure, and thickness.

4 Nanomachines and nanodevices

Nanomachines and nanodevices are devices that operate at the nanoscale and perform specific functions, such as sensing, actuation, computation, and communication. They are based on various principles, such as molecular motors, nanoelectromechanical systems (NEMS), nanofluidics, and nanophotonics. They have potential applications in various domains, such as medicine, biotechnology, information technology, and security. However, they are also influenced by cyclic loading in some scenarios, such as switching, oscillation, and rotation. Nanomechanics modeling and simulation can help analyze the dynamic response, stability, and reliability of nanomachines and nanodevices under cyclic loading, and optimize their design, fabrication, and operation.

5 Nanoscale contact and friction

Nanoscale contact and friction are the phenomena that occur when two surfaces interact at the nanoscale, such as sliding, rolling, or tapping. They are important for the function and performance of many nanosystems, such as nanobearings, nanoswitches, nanomanipulators, and nanotribometers. However, they are also affected by cyclic loading in some situations, such as repeated contact, wear, and lubrication. Nanomechanics modeling and simulation can help understand the mechanisms, effects, and control of nanoscale contact and friction under cyclic loading, and optimize the surface properties, materials, and environment.

6 Nanoscale damage and healing

Nanoscale damage and healing are the processes that involve the initiation, propagation, and repair of defects and cracks at the nanoscale, such as dislocations, vacancies, and interstitials. They are relevant for the durability and functionality of many nanomaterials and nanostructures, such as nanocrystals, nanofibers, and nanolattices. However, they are also influenced by cyclic loading in some cases, such as fatigue, creep, and irradiation. Nanomechanics modeling and simulation can help investigate the mechanisms, kinetics, and thermodynamics of nanoscale damage and healing under cyclic loading, and optimize the defect engineering, self-healing, and recovery strategies.
