“…Exploring the mechanical properties of lunar meteorites and their constituent minerals offers researchers valuable insights, enabling the extrapolation of these properties to the larger scale of lunar rocks, suitable for manufacturing. In this regard, Tang et al (2022) emphasize the significant role of interphases between minerals and microcracks in determining rock mechanics. Such knowledge is fundamental for developing manufacturing processes and techniques adapted to lunar conditions and materials.…”

This study analyzes the mechanical and elemental properties of lunar meteorites DHOFAR 1084, JAH 838, NWA 11444, and HED meteorite NWA 6013. Utilizing microscale rock mechanics experiments, that is, nanoindentation testing, this research reveals significant heterogeneity in both mechanical and elemental attributes across the mineral samples. Olivines, pyroxene, feldspar, and spinel demonstrate similar compositional and mechanical characteristics. Conversely, other silicate and oxide minerals display variations in their mechanical properties. Terrestrial olivines subjected to nanoindentation tests exhibit increased hardness and a higher Young's modulus than their lunar counterparts. A linear correlation is observed between the H/Er ratio and both plastic and elastic energies. Additionally, the alignment of mineral phases along a constant H/Er ratio suggests variations in local porosity. This study also highlights the need for further research focusing on porosity, phase insertions within the matrix, and structural orientations to refine our understanding of these mechanical characteristics. The findings have direct implications for in situ resource utilization strategies and future state‐of‐the‐art impact models. This comprehensive characterization serves as a foundational resource for future research efforts in space science and mining.

“…The AFM (Dimension Icon) was used to measure the geometry and mechanical properties of the interphases between different minerals. The Young's modulus of the interphase was characterized at the microscale by AFM in Tang et al (2022) to provide a modeling parameter. To date, experimental data on the failure properties of interphases are quite limited.…”

“…An accurate grain‐based numerical model (see Figure 1) with a height of 20 mm and a width of 10 mm was applied to simulate uniaxial compression of granite (Tang et al., 2022). This model was then used for calibrating microparameters of interphase that could not be directly measured by tests, as well as for investigating the evolution of macroscale mechanical properties of granite.…”

Owing to changes in temperature with time in active tectonic setting, for example, melt migration and magma-chamber formation, vast volumes of crustal rock will develop extensive microcracks in response to thermal loading (Johnson et al., 2021), which has a significant influence on their physical and mechanical properties. The damage horizon might occur at depths of 5 km geothermal fields or at greater depths where thermal gradients can reach >120°C/km (Marini & Manzella, 2005). Since granites are considered the target formation for deep geothermal energy, understanding and controlling the mechanical behavior of granites under thermal loading are critical for geothermal exploration from hot dry rock (Aghahosseini & Breyer, 2020;Salimzadeh et al., 2018). Thermally induced cracking has been identified as the cause of the reduced strength and enhanced permeability of rock at high temperatures (Nasseri et al., 2009). Furthermore, the reduction of friction coefficient (Du et al., 2022) at elevated temperatures and pore fluid pressures may potentially promote fault destabilization

“…Therefore, it is imperative to explore the dynamic law of rock fracture and seepage under the coupled stress-hydro effect and carry out the prediction research of water damage accidents to reduce the occurrence rate of geotechnical engineering accidents. It has been found, that when the rock breaks, it usually releases electromagnetic energy [26][27][28][29][30][31], elastic energy [32][33][34][35][36][37][38][39][40][41], thermal energy [42][43][44], acoustic energy [45][46][47][48][49][50][51], and other kinds of energy [52]. Hence, generating a variety of disaster warning methods related to rock mass, such as infrared radiation method [53,54], electromagnetic radiation method [55,56], acoustic emission method [57,58], potential method [51,59] and microseismic method [60,61].…”

Effective monitoring of rock fracture and seepage is an important information means to ensure the safety of geotechnical engineering. Therefore, sandstone samples were subject to uniaxial compression under different hydraulic conditions in the presence of infrared radiation and observation. This study uses the multiple infrared radiation indexes (ΔAIRT, IRV, VDIIT) and image data to analyze the influence of coupled stress-hydro effect of infrared radiation change on sandstone surface. The main findings are: (1) The surface temperature of sandstone samples rises in the compaction and linear elastic stages, keeps stable or decreases in the fracture development stage, and rapidly decreases in the post-peak failure stage. (2) The samples with internal water pressure not more than 0.30 MPa, surface temperature and load curve at the compaction and linear elastic stage have a strong power function relationship, which a coefficient of determination is 0.8900. (3) The IRV curve appears as a pulse jump at the time of water seepage. After that, both the fracture development and the post-peak failure stages have stepped up. The VDIIT curve also appears to be a pulse jump at the time of water seepage, and obvious up and down fluctuations exist before water seepage and fracture. (4) Based on the Pauta Criterion, by analyzing the values of VDIIT during the experiment, the early warning threshold of sandstone fracture seepage is determined to be 0.00559. The research finding can provide an experimental and theoretical basis for the early warning of flood accidents in underground rock engineering.
