| Abstract: | To reveal the dynamic mechanical properties of magnesium oxychloride cement-stone powder (MOCSLP) after freeze-thaw cycles under high strain rates, a computational model of the split Hopkinson pressure bar was constructed using ANSYS/LS-DYNA. The dynamic impact process under different impact velocities was simulated, combined with the variable of 0-20 freeze-thaw cycles. The dynamic stress-strain response, energy absorption characteristics, and failure morphology evolution were analysed. The entire dynamic damage process of specimens was tracked also. Results show that MOCSLP exhibits significant strain rate hardening effects. MOC-SLP still maintains strain rate sensitivity after freeze-thaw cycles, but the hardening amplitude decreases, reflecting the dynamic load-bearing potential of damaged specimens. As the number of freeze-thaw cycles increases, the failure mode of specimens transforms from axial tensile failure to shear-tensile composite failure, with aggravated brittle failure characteristics and more fragmented failure morphology. This study provides the theoretical support for their application in impact and explosion protection environments. [ABSTRACT FROM AUTHOR] |
