Mechanical response characteristics and damage mechanism of water-containing mudstone under low strain rate dynamic loading by Guichen LI, Sen YANG, Yuantian SUN, Jinghua LI, Haoran HAO, Zeyu SHAO

“…The mechanisms of fine-scale structural evolution of mudstones under water-rock and dynamic loading were revealed. The results show that: ① low strain rate dynamic loading still has a weakening effect on the strength of mudstone, the ability of mudstone to resist the disturbance of dynamic loading decreases with the increase of water content, dynamic loading rate, and strength, and the strength damage reaches the maximum of 28.47%, 59.76%, and 31.56%, respectively. ② The acoustic emission characteristic parameter law shows that during the loading process, the mudstone has gone through four fracture evolution stages: initial damage, damage intensification, damage quiescence (exacerbation), and damage development, and the Kaiser effect is more obvious at the lower level of each factor in the dynamic loading perturbation stage, and the Felicity effect is more significant at the higher level of each factor. ③ The loading strain and plastic strain of the mudstone under the initial dynamic load disturbance are the largest, and the time of the second significant damage of the mudstone is advanced at higher levels of each factor. …”
