Creep Behavior and Its Prediction of Saturated Weakly Cemented Medium-Grained Sandstone under Multiaxial Loadings

Geofluids (2023)

Qingheng Gu Guangming Zhao Xiangrui Meng Jian Sun Xiang Cheng

Weakly cemented medium-grained sandstone in Ordos mining area of China is widely distributed under phreatic water. The creep behavior of saturated rock is important for the stability of water-resisting strata. In this paper, creep mechanical properties of saturated medium-grained sandstone were studied by triaxial rheological test. The results showed that medium-grained sandstone only shows attenuation creep and stable creep under low stress level, and accelerated creep occurs when axial load reaches about 75% of instantaneous compressive strength. The rock samples exhibit volume dilatancy under most loading levels and finally shear fracture. The failure mechanism is the dislocation separation of mineral particles. Based on the energy dissipation theory, the damage evolution equation was modified and introduced into the Burgers model, which can accurately describe the rheological behavior of saturated medium-grained sandstone. The modified model was used to predict the crack initiation time under different deviatoric stresses, which can provide guidance for early warning of water-resisting rock stability.

Nonlocal composite media in calculations of the Casimir force

Physical Review A (2014)

Jian Sun Yang Huang Lei Gao

The Casimir force between two inhomogeneous metal-dielectric composite slabs with spatial dispersion is investigated theoretically. The equivalent permittivity and permeability of the nonlocal metallic nanosphere is originally derived based on full-wave nonlocal Mie theory. We then adopt two nonlocal effective medium models to study the effective permittivity and permeability of the composite slabs and calculate the Casimir force with Casimir-Lifshitz theory. Due to the excitation of the longitudinal modes, the attractive Casimir force between nonlocal composite materials is much weaker than that of the local composites, and numerical results show that the relative errors between local and nonlocal calculations of Casimir force can be on the order of $25%$. Moreover, the nonlocal effects on the Casimir force are strongly dependent on the microstructures, and they become significant near the percolation threshold of the composite media. The study may be of great interest for making a precise comparison between theoretical and experimental results on the Casimir force between inhomogeneous composite materials.
