Strain Rockbursts Simulated by Low-Strength Brittle Equivalent Materials [PDF]
Advances in Materials Science and Engineering, 2016 This paper presents experimental study on rockbursts that occur in deep underground excavations. To begin with, the boundary conditions for excavation in deep underground engineering were analysed and elastic adaptive boundary is an effective way to ...

Journal of Materials Research and Technology, 2022 We propose a method for obtaining reliable wide strain range equivalent stress–strain curves from tensile testing by applying 3D digital image correlation. Herein, both the front and side surfaces of the specimen were identified by the 45° tilting of the

Residual Strength Estimation Method of Soft Coal Based on Equivalent Residual Strain Ratio
Geofluids, 2022 In underground mining engineering, the residual strength of surrounding rock has an important influence on the secondary stress distribution caused by excavation. Generally, the residual strength of coal can be measured by experiments, but for soft coal,
