Abstract: To investigate the acoustic emission (AE) characteristics and damage mechanical behaviors of Huashan granite, two groups of uniaxial compression tests were carried out: the first group of tests was performed on samples ...

Abstract: The mechanical behaviors of rock under the combined action of high temperature and cyclic loading are a current concern in rock mechanics. In this study, biotite granite samples were thermally treated at the temperatures ...

Abstract: In order to solve the problem of rotor-rotor inter-shaft labyrinth seal rubbing fault during the test run of a counter-rotating dual-rotor aero-engine, based on the fast Fourier transform, the vibration time-domain signals ...
