“…In terms of the peak strength, it increases when the applied strain rate changes from 0.01 s −1 to 0.001 s −1 , while it decreases as the applied strain rate increase from 0.001 s −1 to 0.0001 s −1 , suggesting that the compressive maximum stress lies within the range of strain rates corresponding to the brittle-to-ductile transition behavior. 49 This is consistent with previous findings [49][50][51][52] that the compressive maximum stress occurs at a strain rate of approximately 0.001 s −1 . In contrast, for polycrystalline THF hydrates, the compressive peak stress increases as the strain rate decreases, which differs from the case of polycrystalline ice.…”

“…In contrast to regular soil, the mechanical properties of frozen soil under impact load show obvious strain rate effect, that is, the strength limit of frozen soil increases with the increase of loading strain rate, which is common in ice structure 42 , 43 . When the frozen soil is subjected to high-strain rate loads such as impact and explosion, the adiabatic temperature rise will occur inside the permafrost.…”
