Computer simulation of impact-induced particle breakage
The breakage induced in single circular particles that impact on solid plates has been studied using a two-dimensional simulation of solid fracture. The simulation allows the computer 'experimenter' to vary independently material properties such as Young's modulus, Poisson's ratio and work of fracture, flexibility that is unavailable in direct experimentation. Where comparison is possible, the ...

15 صفحه اولParametric dependence of particle breakage mechanisms
It has been observed that the pattern of particle impact breakage in two-dimensional systems is a result of two mechanisms. AMechanism IB accounts for the breakage induced by the stresses that appear in unbroken particles. AMechanism IIB breakage is due to the buckling of the Mechanism I fragments. The purpose of this paper is to try and understand the parameters that govern the magnitude of th...
متن کاملMicromechanical Considerations of Particle Breakage Using Discrete Element Method
Using DEM (Discrete Element Method), a model is presented to simulate the breakage of two-dimensional polygonshaped particles. In this model, shapes of the particles generated after breakage are predefined and each uniform (uncracked) particle is replaced with smaller inter-connected sub-particles. If the bond between these sub-particles breaks, breakage will happen. With the help of this model...
متن کاملSimulation of Cold Rolling Process Using Smoothed Particle Hydrodynamics (SPH)
Regarding the reported capabilities and the simplifications of the smoothed particle hydrodynamics (SPH) method, as a mesh-free technique in numerical simulations of the deformation processes, a 2-D approach on cold rolling process was provided. Using and examining SPH on rolling process not only caused some minor developments on SPH techniques but revealed some physical realities. The chosen t...
