Parametric 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 کاملComputer 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 ...
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 کاملFactors Influencing Indices of Competency for Student-Teachers in Physical Education
To identify the indices of competency for student-teachers in Physical Education and factors that influence them, 22 expert were interviewed and 324 student-teachers from all over the country were given a questionnaire. Data analyses revealed that competency has four sets of indices in the areas of subjective-educational, educational, subjective, and general. Factors affecting these competencie...
