Breakage Characterization of Magnetite under Impact Loads and Cyclic Impact Loading [PDF]

open access: yesEnergies, 2020
A series of impact compression tests were conducted to study the breakage characteristics of magnetite, as well as the impact pressure on its strain rate and dynamic compressive strength. The dynamic mechanical properties and fragmentation size distribution of magnetite under diverse impact loads and cyclic impact were investigated, with fractal theory

Experimentally investigating comparison between the behavior of fibrous concrete slabs with steel stiffeners and reinforced concrete slabs under dynamic–static loads

open access: yesOpen Engineering, 2022
Three scaled concrete slabs were cast and tested till failure under drop-weight impacts and static loads, sequentially. Two of the three slabs contained 0.5% steel fiber while the third slab was constructed by using only steel bar reinforcement (i.e ...

A model for fluvial bedrock incision by impacting suspended and bed load sediment [PDF]

open access: yes, 2008
A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load.
