The meso-fracturing mechanism of marble under unloading confining pressure paths and constant axial stress [PDF]
Scientific Reports, 2021 Failure tests on marble during unloading confining-pressure under constant axial stress and simulations with the particle flow code were performed. The influence mechanism of the unloading rate of the confining pressure, initial unloading stress, and ...

Constitutive Model of N15 Propellant considering the Confining Pressure Effect
International Journal of Aerospace Engineering, 2021 To describe the effect of confining pressure on the mechanical responses of N15 propellant, a constitutive model considering the confining pressure effect was first established for N15 propellant based on the elastic-viscoelastic correspondence principle.

Energy dissipation in sheared wet granular assemblies [PDF]
, 2018 Energy dissipation in sheared dry and wet granulates is considered in the presence of an externally applied confining pressure. Discrete element simulations reveal that for sufficiently small confining pressures, the energy dissipation is dominated by ...
