TL;DR: In this paper, a discrete fragmentation multigenerational approach is applied as a spawning procedure for elasto-brittle spheres to represent failure of grains isolated between platens or within granular masses.
Abstract: In this study oedometric compression tests of hydrocarbon coke, Fontainebleau sand and silica sand are simulated in three dimensions using breakable particles. The method adapts a rigorous breakage criterion for elasto-brittle spheres to represent failure of grains isolated between platens or within granular masses. The breakage criterion allows for the effect of particle bulk and contact properties to be treated separately. A discrete fragmentation multigenerational approach is applied as a spawning procedure. The number of particles quickly increases during the simulation, but is kept manageable by systematic fine exclusion and upscaling. Fine exclusion leads to mass losses between generations, but that loss is accounted for outside the mechanical model. Sensitivity analysis shows that it is enough to keep 53% of the crushed particle mass within the mechanical model to correctly reproduce experimental macroscopic behaviour. Practical upscaling rules are proposed for (a) contact stiffness, (b) breakage c...

TL;DR: It is shown that the nonlinear response of the model acts as a bounded disturbance, which is used to elaborate an adaptive controller, to prove the closed-loop stability and to obtain performance bounds.

TL;DR: In this article, the authors estimate that irrigation of annual fruits and vegetables produces 26 hm 3 y 1 of groundwater recharge in the Campo de Cartagena area of southeast Spain, where irrigation return flow accounts for a substantial portion of recharge.
