This third of three volumes includes papers from the second series of NODYCON, which was held virtually in February of 2021. The conference papers reflect a broad coverage of topics in nonlinear dynamics, ranging from traditional topics from established streams of research to those from relatively unexplored and emerging venues of research. These include

• Complex dynamics of COVID-19: modeling, prediction and control
• Nonlinear phenomena in bio-systems and eco-systems
• Energy harvesting
• MEMS/NEMS
• Multifunctional structures, materials and metamaterials
• Nonlinear waves
• Chaotic systems, stochasticity, and uncertainty
