Generalities on Constitutive Models
2023The balance equations of a body form an under-determined differential system, insufficient to yield specific results unless further relations are supplied. The balance equations for a continuum (free from internal structures) are the continuity equation, the equation of motion, and the balance of energy, namely five equations, for the fourteen unknowns

A statistical damage constitutive model considering whole joint shear deformation
International journal of damage mechanics, 2020The whole shear deformation of rock joints significantly affects the long-term behavior and safety of engineering projects. In this paper, a new damage constitutive model related to the Weibull distribution and statistical damage theory is proposed. This

A path dependent constitutive model for CFFT column
, 2020Confinement, such as hollow-steel tube (HST) and fibre-reinforced polymer (FRP) tube, can improve not only the loading capacity of concrete structures, but also ductility. Compared with HST, FRP tube has stronger flexural and tensile strength, as well as

A damage constitutive model for shear behavior of joints based on determination of the yield point
, 2020Rock joints, a ubiquitous geological phenomenon, greatly affect the mechanical properties of rock masses for engineering purposes. The shear constitutive model of rock joints plays an important role in the research in this field, both experimentally and ...

Dual-damage constitutive model to define thermal damage in rock
, 2020The evolution of the mechanical properties of rock as a function of thermal damage is relevant to various engineering applications, such as nuclear waste repositories, underground coal gasification, dry-fracture shale system and geothermal energy ...

Isotropic damage constitutive model for time-dependent behaviour of tunnels in squeezing ground
, 2020The conventional constitutive models employed to describe rock mass creep behaviour associated with the squeezing mechanism are widely adopted in research and design practice. However, these models fail to explicitly replicate the 3-phase creep behaviour

Tunnel excavation in squeezing ground is very challenging due to the difficulty in making reliable predictions at the preliminary design stage. Tunnel response in squeezing ground is made possible by employing creep constitutive models.
