... Abstract In this paper, a detailed analysis is made to detect the morphology of Xuzhou marble from room temperature to 1400° using polarizing microscope and combine it with acoustic emission characteristic parameters from 200° to 800°. Some results are achieved: the marble samples would...

..., uniaxial and triaxial compression tests on the Beishan granite were conducted using a servo-controlled compression system. The rock samples were taken from 560 to 575m below the ground surface in the Xinchang rock block of the Beishan area, China. Acoustic emission (AE) monitoring combined with stress...
