Dynamic Simulation of Rock‐Avalanche Fragmentation
Journal of Geophysical Research F: Earth SurfaceAbstractFragmentation is a common phenomenon in complex rock‐avalanches. The fragmentation intensity and process determines exceptional spreading of such mass movements. However, studies focusing on the simulation of fragmentation are still limited and no operational dynamic simulation model of fragmentation has been proposed yet.

Rock and Soil Mechanics, 2022 Particle impact, a new drilling technology, has been applied in drilling and gas and oil exploitation. Also, it is considerably promising as an assisting rock-breaking method for the excavation of tunnels in extremely hard rocks.

Merging and fragmentation in the Burgers dynamics [PDF]
Physical Review E, 2010 We explore the noiseless Burgers dynamics in the inviscid limit, the so-called ``adhesion model'' in cosmology, in a regime where (almost) all the fluid particles are embedded within point-like massive halos. Following previous works, we focus our investigations on a ``geometrical'' model, where the matter evolution within the shock manifold is defined

Short communication: Runout of rock avalanches limited by basal friction but controlled by fragmentation [PDF]
Earth Surface Dynamics, 2021 Rock avalanches produce exceptionally long run-outs that correlate with their rock volume. This relationship has been attributed to the size-dependent dynamic lowering of the effective basal friction.

Plate-impact-driven ring expansion test (PIDRET) for dynamic fragmentation [PDF]
EPJ Web of Conferences, 2021 A new experimental set-up mounted at the muzzle of a singlestage gas gun has been designed in order to study the fragmentation of metallic rings under dynamic radial expansion.

Dynamic Buckling and Fragmentation in Brittle Rods [PDF]
Physical Review Letters, 2005 We present experiments on the dynamic buckling and fragmentation of slender rods axially impacted by a projectile. By combining the results of Saint-Venant and elastic beam theory, we derive a preferred wavelength lambda for the buckling instability, and experimentally verify the resulting scaling law for a range of materials including teflon, dry ...

Software protection technology based on code fragmentation
网络与信息安全学报, 2020 Aiming at the shortcomings of the current software protection technology, a code fragmentation technology was proposed. This technology is a new software protection technology that takes functions as units, shells functions, randomizes memory layout, and

The effect of rare earth elements on the work softening behavior of as-cast Mg-4Al-2Sn
Materials Research Express, 2020 This work explores the addition of 1% Rear Earth (RE) elements on the Mg–4Al–2Sn magnesium alloy, with an emphasis laid on the microstructural evolution during solidification and subsequent hot deformation behavior.
