Numerical modelling of time-dependent deformation around an underground mine in rock salt

The stress field and the time dependent deformation around a solution cavity in rock salt are shown to be sensitive to the details of the excavation process and to the prevailing tectonic stress field. An analysis procedure is developed whereby an incremental excavation procedure and a creep routine are incorporated simultaneously into an axisymmetric finite element code.

Hydroxyl Masers

AbstractThe statistical rate equations are used to model the OH masers to see if they will always have a one-to-one correspondence with the variation of dust temperature. It is concluded that one has to be careful to argue that the masers will always follow the dust temperature variation profile, and it is possible that different maser transitions from the same molecule respond differently to the same dust temperature variations.
