“…Therefore, EOS must be introduced to rectify the relationship between volume, pressure, and internal energy. For metals, the Mie-Grüneisen EOS [49,50] exhibits robust performance, as validated by numerous research papers, including our previous study [51]. It establishes a relationship between the pressure and volume of a solid at a specific temperature, thereby determining the instantaneous pressure of an impact-compressed solid.…”

“…Numerous publications have extensively covered failures and damages during tensile wave interactions [64][65][66]. The absence of damage models in this study limits our investigation of possible spall phenomena similar to those explored in our previous work [51]. To elucidate the differences in the free surface velocity of the backplate observed in distinct layer sequence configurations, we extended our investigation to include a comparison of strain energy and kinetic energy between the initial impact on the front layer (the impactor hits the front layer) and the subsequent impact on the backplate (the composite assembly hits the backplate).…”

“…Our previous investigation [51] successfully employed the plate impact simulation method to study the dynamic response of metals under high-strain-rate loading using the Johnson-Cook model with the Mie-Gruneisen EOS. Due to their exceptional resistance to ultra-high-strain-rate impacts, metals excel in extreme impact-mitigation applications, effectively handling velocities exceeding thousands of meters per second.…”

This paper presents a numerical study on the dynamic response and impact mitigation capabilities of layered ceramic–polymer–metal (CPM) composites under plate impact loading, focusing on the layer sequence effect. The layered structure, comprising a ceramic for hardness and thermal resistance, a polymer for energy absorption, and a metal for strength and ductility, is analyzed to evaluate its effectiveness in mitigating the impact loading. The simulations employed the VUMAT subroutine of DSGZ material models within Abaqus/Explicit to accurately represent the mechanical behavior of the polymeric materials in the composites. The VUMAT implementation incorporates the explicit time integration scheme and the implicit radial return mapping algorithm. A safe-version Newton–Raphson method is applied for numerically solving the differential equations of the J2 plastic flow theory. Analysis of the simulation results reveals that specific layer configurations significantly influence wave propagation, leading to variations in energy absorption and stress distribution within the material. Notably, certain layer sequences, such as P-C-M and C-P-M, exhibit enhanced impact mitigation with a superior ability to dissipate and redirect the impact energy. This phenomenon is tied to the interactions between the material properties of the ceramic, polymer, and metal, emphasizing the necessity of precise material characterization and enhanced understanding of the layer sequencing effect for optimizing composite designs for impact mitigation. The integration of empirical data with simulation methods provides a comprehensive framework for optimizing composite designs in high-impact scenarios. In the general fields of materials science and impact engineering, the current research offers some guidance for practical applications, underscoring the need for detailed simulations to capture the high-strain-rate dynamic responses of multilayered composites.
