RISGeotechnical Properties of the Icy Lunar Regolith in Cryogenic Environments Anticipated in Permanently Shadowed Regions of the Moon
Publisher: ASCE
Abstract: Ever since the Lunar Crater Observation and Sensing Satellite (LCROSS) data helped confirm the presence of water in the permanently shadowed regions (PSRs) of the lunar polar area, interest in developing systems for the ...
Comprehensive Evaluation of Strength Criteria for Granite, Marble, and Sandstone Based on Polyaxial Experimental Tests
Publisher: ASCE
Abstract: Cubic specimens of three rocks—granite, marble, and sandstone, representing very strong rock, moderately strong rock, and weak rock, respectively—were tested under polyaxial stress. The objective was to determine the optimal ...
Numerical Investigation of Hard Rock Strength and Fracturing under Polyaxial Compression Based on Mogi-Coulomb Failure Criterion
Publisher: American Society of Civil Engineers
Abstract: Failure characteristics of rocks under polyaxial compression have been the subject of extensive laboratory testing, although a limited amount of literature is published on the numerical simulation of rock failure under ...
