Discontinuous Fatigue Mechanical Properties for Rock Salt
摘要
The previous chapter introduced the conventional fatigue and properties for rock salt. Conventional fatigue and creep means the material is subjected to continuous loading. However, in reality geomaterials the loading typically is regular, but randomly interrupted a reactivated. For instance, Germany Huntorf plant completes one cycle every day (Cyran in Arch Mining Sci 65(2), 2020 [1]). The underground salt CAES works 10 h and stop 14 h During the period of stop, the air pressure inside CAES is constant. Whether this pressure plateau would exert influence on the fatigue properties is unclear.
