Acoustic emission (AE) characterization is an effective technique to indirectly capture the failure process of quasi brittle rock. In previous studies, both experiments and numerical simulations were adopted investigate AE characteristics rocks. However, as most popular model, moment tensor model (MTM) cannot be constrained by experimental result because there a gap between MTM in principle, signal processing energy analysis. this paper, we developed particle-velocity-based (PVBM) that...
Typically, a rock's direct tensile strength (DTS) is lower than its Brazilian splitting (BTS). This disparity becomes more pronounced when subjected to thermal damage. However, comparative and in-depth analysis of the mechanisms underlying these disparities remains lacking. We experimentally investigated behaviors crystalline rocks exposed different heat-treated temperatures. The curve dog-bone shaped samples showed declines in peak stress, slope, failure displacement with increasing...
ABSTRACT This study investigates the effects of thermal damage on tensile behavior granite during Brazilian splitting tests, focusing negative Poisson's ratio (NPR) effect. Using digital image correlation and acoustic emission techniques, research reveals that increasing from 25°C to 800°C reduces strength by up 85.7% induces a brittle‐to‐ductile transition. The NPR effect emerges, intensifies, subsequently disappears as temperature increases, significantly altering stress distribution...
