Abstract
Void nucleation and growth under dynamic loading are essential for damage initiation and evolution in ductile metals. In the past few decades, the development of experimental techniques and simulation methods has helped to reveal a wealth of information about the nucleation and growth process from its microscopic aspects to macroscopic ones. Powerful and effective theoretical approaches have been developed based on this information and have helped in the analysis of the damage states of structures, thereby making an important contribution to the design of damage-resistant materials. This Review presents a brief overview of theoretical models related to the mechanisms of void nucleation and growth under dynamic loading. Classical work and recent research progress are summarized, together with discussion of some aspects deserving further study.

Summary
The development of modern industry has prompted the exploration of material properties under extremely complex service conditions. For materials ranging from traditional ones that have been used for centuries to recently designed ones relying on new manufacturing technologies, studies of performance under extreme service conditions provide an indispensable basis for their applications in a wide variety of fields, such as defense-related and astronautics industries, the nuclear industry, and nano-manufacturing.. For materials ranging from traditional ones that have been used for centuries to recently designed ones relying on new manufacturing technologies, studies of performance under extreme service conditions provide an indispensable basis for their applications in a wide variety of fields, such as defense-related and astronautics industries, the nuclear industry, and nano-manufacturing.14,15 In this context, the mechanical responses of ductile metals under high-strain-rate loading conditions are of great interest, including their dynamic yielding behavior and dynamic fracture process.
