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.

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 ...

Nano-confinement effects on liquid pressure [PDF]
Physics of Fluids, 2021 In this study, molecular dynamics simulations are performed to estimate the equilibrium pressure of liquid confined in nanopores. The simulations show that pressure is highly sensitive to the pore size and can significantly change from absolute positive to absolute negative values for a very small (0.1 nm) change in the pore size. The contribution from

Pressure-Induced Melting of Confined Ice [PDF]
ACS Nano, 2017 The classic regelation experiment of Thomson in the 1850s deals with cutting an ice cube, followed by refreezing. The cutting was attributed to pressure-induced melting but has been challenged continuously, and only lately consensus emerged by understanding that compression shortens the O:H nonbond and lengthens the H-O bond simultaneously.

Modulus–pressure equation for confined fluids [PDF]
The Journal of Chemical Physics, 2016 Ultrasonic experiments allow one to measure the elastic modulus of bulk solid or fluid samples. Recently such experiments have been carried out on fluid-saturated nanoporous glass to probe the modulus of a confined fluid. In our previous work [G. Y. Gor et al., J. Chem.
