When the rotation angle θ 2 was less than 30°, the RTRH structure exhibited obvious signs of contraction after pore compression, indicating a significant negative Poisson’s ratio effect, but its rotational deformation phase was shortened; when θ 2 is greater than 30°, the rotational deformation phase of the RTRH structure increased, but the structure showed a trend of expansion during compression, and the negative Poisson’s ratio phenomenon was reduced.
