The effect of different fracture mechanisms on impact fragmentation of brittle heterogeneous solid
International Journal of Impact Engineering, 2018Abstract The fragmentation of brittle and heterogeneous spherical solids under impact loading is numerically studied using the combined finite and discrete element method (FDEM) and cohesive crack model. The effect of different fracture mechanisms on the dynamics and statistics of fragmentation is investigated by adjusting the failure criterion of ...

Excitation of nuclear reaction under mechanical effect (impact) on deuterated solids
Physica B: Condensed Matter, 1990Abstract Using the analysis data on the characteristics of radiation accompanying failure of solids as the basis, a supposition is made of the feasibility of dd-reactions taking place during fracture of deuterated dielectrics. The experiments carried out prove the feasibility of generation of neutrons at the moment of fracture of D 2 O LD crystals ...

International Journal of Mechanical Sciences, 2021
Abstract In this paper, the mechanism and parameters affecting the contact time of droplet impacting on the solid surface were studied by incorporating numerical simulation method and water spring theory. An empirical correlation of dimensionless contact time was obtained and an exploring idea with the application of wettability-controlled surface ...

Explosion-like chemical reactions in solids initiated by mechanical impact
Russian Journal of Physical Chemistry B, 2016The mechanical behavior and physicochemical transformations in a number of halide vinyl polymers and hydrogen-free inorganic oxidizers subjected to a mechanical impact are studied experimentally and theoretically to gain insights into explosive-like reactions in solids.

Mechanisms of solid particle erosive wear for 90° impact on copper and iron
Wear, 1981Abstract High purity copper single crystals and fully annealed polycrystalline α-Fe were eroded by glass spheres 70 μm in diameter suspended in an argon gas stream and travelling normal to the target surface at 122 m s−1. Detailed scanning electron microscopy of eroded surfaces, together with transmission electron microscopy of erosion debris, was ...

Multiple-impact mechanisms on Venus and other solid planets and satellites
Earth, Moon, and Planets, 1991While atmospheric pressure can be considered a major multiple impact mechanism on Venus, probable mechanisms for multiple impacts on other solid planetary bodies cannot be isolated with certainty.

Thermal impact—the mechanical response of solids to extreme electromagnetic radiation
Planetary and Space Science, 1961Abstract The phenomenon of thermally induced stress waves resulting from the deposition by radiation of intense electromagnetic energy into the surface of a solid is described. Both theoretical and experimental aspects are treated. The derivation and general solution for the case of a semi-infinite bar are given.

Mechanism Wear of Elastomers with Oblique Impact of Solid Particles in the Aqueous Medium
Journal of Friction and Wear, 2019An experimental study made it possible to identify the stages and mechanism of deterioration of a rubber surface in an aqueous medium for conditions of impact with a single solid particle and impact with a hydroabrasive jet. The deterioration has a fatigue character and is divided into two stages: formation of the primary site of deterioration and ...

On the mechanism of molecular ion formation from organic solids by ion impact
Nuclear Instruments and Methods in Physics Research, 1982Abstract The general behaviour of transitions from bound molecular surface states into dissipative gaseous states in an externally dc-field-free region is reviewed. Adiabatic and non-adiabatic processes have to be distinguished. It is shown that non-adiabatic interactions may be responsible for various phenomena of molecular ion formation by heavy ...
