    Constitutive Model of Rock Uniaxial Damage Based on Rock Strength Statistics by Ming Ji, Kai Chen, Hong Jun Guo

    Published 2018-01-01
    “…Based on the assumption that rock strength follows the log normal distribution statistically, this paper establishes a damage constitutive model of rock under uniaxial stress conditions in combination with the Mohr–Coulomb strength criterion and damage mechanical theory. …”

    Features and Constitutive Model of Gypsum’s Uniaxial Creep Damage considering Acidization by Wei Chen, Wen Wan, Senlin Xie, Wenlong Kuang, Wenqing Peng, Qiuhong Wu, Shasha Tong, Xianqing Wang, Xiaoyu Tang

    Published 2020-01-01
    “…Due to the rapid increase, the surfaces of the samples are almost like “holes”. (3) A new nonlinear creep constitutive model was established by connecting Burgers model with nonlinear viscoplastic body (NVPB) model in series, which can well describe the creep characteristics of gypsum rocks under acid corrosion.…”

    Study of Damage Constitutive Model of Brittle Rocks considering Stress Dropping Characteristics by Fei Li, Shuang You, Hongguang Ji, Hao Wang

    Published 2020-01-01
    “…Based on the damage constitutive model considering residual strength characteristics, a correction factor reflecting stress dropping rate is added, the Weibull distribution is used to describe the inhomogeneity of rock materials, and Drucker–Prager criterion is used to quantitatively describe the influence of stress on damage; a damage constitutive model of deep brittle rock considering stress dropping characteristics is established. …”
