Numerical Simulation and Evaluation on Continuum Damage Models of Rocks

Autor: Leilei Zhao, Zhendong Cui, Ruidong Peng, Kai Si

Publikováno v: Energies, Vol 15, Iss 18, p 6806 (2022)

Damage mechanics play an important role in the analysis of rock deformation and failure. Numerous damage variables have been proposed and the corresponding continuum damage models were suggested. Knowing how to apply these theoretical models appropri

Study on Fatigue Life Prediction and Acoustic Emission Characteristics of Sandstone Based on Mesoscopic Crack Propagation Mechanism

Autor: Kai Si, Zhendong Cui, Ruidong Peng, Leilei Zhao

Publikováno v: Energies, Vol 15, Iss 13, p 4807 (2022)

Even when the maximum stress is less than the peak stress under conventional loading, fatigue failure of rock is likely to occur, thereby showing its unique characteristics. The present study summarized the factors affecting rock fatigue life from th

Numerical Simulation on Mesoscale Mechanism of Seepage in Coal Fractures by Fluid-Sloid Coupling Method

Autor: Kai Si, Ruidong Peng, Leilei Zhao, Yan Zhao, Yaheng Zhu, Zhendong Cui, Jianyong Zhang

Publikováno v: Geofluids, Vol 2021 (2021)

Trying to reveal the mechanism of gas seepage in coal is of significance to both safe mining and methane exploitation. A series of FEM numerical models were built up and studied so as to explore the mesoscale mechanism of seepage in coal fractures. T

Comparative Study on Mineral-Scale Microcrack Propagation of Shale under Different Loading Methods

Autor: Jianyong Zhang, Zhendong Cui, Weige Han, Kai Si, Yan Zhao

Publikováno v: Advances in Civil Engineering, Vol 2021 (2021)

Producing a sufficient volume of multiscale crack networks is key to enhancing recovery of shale gas. The formation of crack network largely depends on initiation and propagation of microcracks. To reveal the influence of different loading methods on

Crack Propagation Process and Seismogenic Mechanisms of Rock Due to the Influence of Freezing and Thawing

Autor: Kai Si, Zhendong Cui, Ruidong Peng, Leilei Zhao, Yan Zhao

Publikováno v: Applied Sciences, Vol 11, Iss 20, p 9601 (2021)

A common problem in cold regions is the influence of freeze–thaw damage on the stability of rock engineering. Therefore, a series of uniaxial compression tests of sandstone after freeze–thaw treatment was carried out in this study. The purpose wa
