Chain-mail fabric stiffens under confining pressure [PDF]

Nature, 2021
The mechanical properties of chain mail have been revisited. The findings reveal that, under confining pressure, chain-mail-inspired materials can switch from pliable to stiff structures that have outstanding load-bearing capacities. Pliable materials that undergo a jamming transition.

Finite-Element Analysis of Shear-off Failure of Keyed Dry Joints in Precast Concrete Segmental Bridges [PDF]

, 2014
This article has been made available through the Brunel Open Access Publishing Fund.The structural behaviour of precast concrete segmental bridges is largely dependent on the behaviour of the joints between segments.

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.

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 ...

Numerical Analysis of Cyclic Impact Damage Evolution of Rock Materials under Confining Pressure

Applied Sciences, 2023
To study the effect of cyclic impacts and confining pressure on the damage evolution of rock materials, numerical simulations of cyclic impact tests on rock materials under confining pressure were carried out by LS-DYNA using dynamic relaxation and full ...

Acoustic waves in granular packings at low confinement pressure [PDF]

Review of Scientific Instruments, 2020
Elastic properties of a granular packing show a nonlinear behavior determined by its discrete structure and nonlinear inter-grain force laws. Acoustic waves show a transition from constant, pressure-dependent sound speed to a shock-wave-like behavior with an amplitude-determined propagation speed.
