Research progress on the thermodynamically plastic deformation of metals at ultra-high strain rates

The research progress of thermodynamic plastic deformation behavior of metals at ultra-high strain rates was reviewed. The macroscopic thermodynamic plastic deformation behavior of metals at ultra-high strain rates and the evolution of their microstructures were summarized from three aspects: experimental research, theoretical model (constitutive relation) and numerical simulation. By systematically sorting out, reviewing and comparing the relevant literatures, the remaining issues in this field were summarized, and several important possible projects on dynamically plastic deformation of metals at ultra-high strain rates were proposed, and to provided the guidance and reference for the following studies of the dynamically plastic deformation at the ultrahigh strain rate. © 2023 Huazhong University of Science and Technology.
