State Key Laboratory for Geomechanics and Deep Underground... under uniaxial compression, and the test data are fitted well with the theoretic formula.Key words:rock mechanics; rock burst proneness; prediction; accumulative acoustic emission counts; Weibull......
J. Cent. South Univ. (2016) 23: 1208-1214 DOI: 10.1007/s11771-016-0370-y Recommendation application for video head impulse test based on fuzzy logic control NGUYEN Thi Anh Dao1, KIM Dae Young2, LEE... while the head is in motion. Nowadays, VOR measurement is commonly done with a video head impulse test based on a velocity gain algorithm or a position gain algorithm, in which velocity gain is a VOR......
before and after tensile test were used to evaluate the fracture behavior.Experimental results show that the fracture surfaces of laminated composites mainly present brittle failure characteristics......
