This paper numerically investigates the seismic response of the filled joint under high amplitude stress waves using the combined finite-discrete element method (FDEM). A thin layer of independent polygonal particles are used to simulate the joint fillings. Each particle is meshed using the Delaunay triangulation scheme and can be crushed when the load exceeds its strength. The propagation of t...

Particle crushing dominates the deformation behaviour of granular materials under significantly high compressive and shear stress. A proposed constitutive model has been verified to predict crushing behaviour of granular materials with different crushability and adopted one kind of reference crushing stress. It is noted that no positive dilatancy of granular material in triaxial test occurs onc...

Numerous industries involve impact crushing of raw material in their processes. Crushing is performed by interaction between raw material witch size is reduced during this process and equipment or parts that crush. Some of the biggest and most important clients of crushing and milling equipment are industries like cement plants, mines, open pits, coal fired thermal plants, recycling and shreddi...

in this paper shear behavior of two calcareous sands having different physical properties areinvestigated using drained and undrained triaxial tests. the investigated sands are obtained from two differentzones located in persian gulf, kish island and tonbak region. analysis based on energy aspects show thatfriction angle in these soils, having crushable particles, is formed of three components:...
