RESEARCH ON KAISER EFFECT DURING CLOSING PERIOD OF ROCK CRACKS UNDER UNIAXIAL LOADING
单轴压缩试验下裂纹闭合阶段岩石KAISER效应的研究

The KAISER effect during closing period of rock cracks under uniaxial loading is studied. The test result shows that KE occurs during closing period of rock cracks and the rocks have the ability to remember their previous stress, strain, Young's modulus, Possion ratio and damage factor. The mechanism of rock's KAISER effect does be remembering its previous damage.
