The stress wave propagation and its effect on the deformation were analyzed by the stress and strain distributions. Industrial pure lead, oxygen-free high-conductivity (OFHC) copper and 7039......
J. Cent. South Univ. (2019) 26: 728-742 DOI: https://doi.org/10.1007/s11771-019-4043-5 Dynamic stress accumulation model of granite residual soil under cyclic loading based on small-size creep... Abstract: The creep behaviors of granite residual soil with pre-stress of 100 kPa was investigated by a series of small size creep tests. Three different types of strain curves were obtained at different......
