Study of Damage and Acoustic Emission Properties of Rocks under Uniaxial Cyclic Load-Unload
In order to study the damage and sptial spatial and temporal distribution of acoustic emission of rocks under uniaxial cyclic load-unload, test of rocks with various kinds of heterogeneity under uniaxial cyclic load-unload disturbance was conducted using numerical simulation software RFPA2D.Figure destruction and acoustic emission - load curve of rocks were obtained from the test.The results show that destroy of the rock was produced from tensile stress concentration area surrounding the hole. as the load increases,crack developmented to the edge of the rock.when homogeneity of rock was low, crack development with irregularity due to defects of rocks. with the increasing homogeneity of rock, damage evolution mode under uniaxial cyclic load-unload disturbance transition from ductile to brittle.damage evolvement process can be responsed by acoustic emission. with the increasing homogeneity of rock. The maximum number of acoustic emission Continuously improve and exhibit unexpected. Kaiser effect of acoustic emission under cyclic loading is significantly This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. .
