NUMERICAL MODELLING OF DISCONTINUA

NUMERICAL MODELLING OF DISCONTINUA Discrete element methods are numerical procedures for simulating the complete behaviour of systems of discrete, interacting bodies. Three important aspects of discrete element programs are examined 1 the representation of contacts 2 the representation of solid material and 3 the scheme used to detect and revise the set of contacts. A proposal is made to define what constitutes a discrete element program, and four classes of such programs are described the distinct element method, modal methods, discontinuous deformation analysis and the momentumexchange method. Several applications and examples are presented, and a list is given of suggestions for future developments. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Engineering Computations Emerald Publishing

Abstract

Discrete element methods are numerical procedures for simulating the complete behaviour of systems of discrete, interacting bodies. Three important aspects of discrete element programs are examined 1 the representation of contacts 2 the representation of solid material and 3 the scheme used to detect and revise the set of contacts. A proposal is made to define what constitutes a discrete element program, and four classes of such programs are described the distinct element method, modal methods, discontinuous deformation analysis and the momentumexchange method. Several applications and examples are presented, and a list is given of suggestions for future developments.
