摘要
在MTS上进行了疲劳加载实验 ,取得了南京砂岩的模量、泊松比、波速都随频率的增高呈非线性增大 ,强度具有明显的各向异性。饱和大理岩具有显著的应力振幅效应和频率效应以及各向异性。
Fatigue loading experiment is conducted on MTS.From the results it can be gained that the modulus,Poisson's ratio and wave velocity of Nanjing sandstone non linearly increase as frequency rising,and the strength is obviously anisotropic.Saturated marble is obviously effected by the amplitude and frequency of applied stress,and is also anisotropic.The influence of stress amplitude on marble is much larger than that of frequency.
