The Special Issue "Dynamic Behavior of Materials" presents fifteen peer-reviewed research articles exploring the dynamic behavior of various materials under high strain rates. The studies cover topics such as microstructural evolution, equations of state, constitutive equations, material and structure under high-velocity impact, explosive-material interaction, and theoretical modeling and simulation. The articles highlight the importance of understanding dynamic material behavior for applications in aerospace, defense, and marine engineering. Key findings include the significant increase in strength of materials under dynamic loading, the role of deformation twins in plastic deformation, and the development of the Johnson–Cook constitutive equation to describe material behavior under high strain rates. The issue also discusses the effects of strain rate on material properties, the influence of microstructure on dynamic behavior, and the challenges in predicting material responses under extreme conditions. The research contributes to the understanding of material behavior under dynamic loading and provides insights for future studies in this field.The Special Issue "Dynamic Behavior of Materials" presents fifteen peer-reviewed research articles exploring the dynamic behavior of various materials under high strain rates.
