A random forest model trained on acoustic emission signals from granite hydraulic fracturing experiments forecast specimen failure up to 1800 ...

A new acoustic emission indicator called WIb issued warnings before failure in all 403 sandstone specimens tested, typically at loads ...

Controlled laboratory experiments found that surrounding conditions most strongly influenced acoustic emission attenuation in metal waveguides, followed by tube diameter ...

Biaxial tests on granite specimens with parallel cement-filled fissures show that steeper structural plane dips delay rockburst triggering but produce ...

Laboratory compression tests on four granites show that stress-induced anisotropy of about 20 percent leaves fracture orientations nearly unchanged but ...

Controlled uniaxial compression tests found that increasing dissolution weakened rock-like specimens and changed failure from a dominant-crack event to progressive ...

New experiments show cement mortar heated to 300 degrees Celsius can gain shear stiffness when cooled slowly in air, but ...

Experiments and simulations reveal that frictional interfaces under shock loading activate globally and emit discrete, quantized longitudinal wave packets that ...

Researchers have created a temperature-pressure optimization atlas that shows when deep coal cores need full five-field preservation and when a ...
