Many atte.pts have.be.n made.to find various re.ationships for diffe.e.t parame.e.s and some.kinds of constitutive.mode.s for studying the.be.avior of particulate.me.ia. All the.e.mode.s are.base. on conce.ts of continuous me.ia. Using a nume.ical me.hod such as discre.e.e.e.e.t me.hod, one.can figure.out what is happe.ing through a discontinuous me.ia whe.e.soil particle. play the.main role.in introducing the.she.r stre.gth and de.ormation characte.istics. The.be.avior of the.me.ia with bre.kable.particle. is studie. in this pape. and compare. with that of the.asse.bly with non-bre.kable.particle.. In this pape., the.hype.bolic e.astic mode. is inve.tigate. for the.asse.bly of polygon shape. particle. in two diffe.e.t te.t se.ie.. In addition, e.olution of diffe.e.t macro parame.e.s of the.asse.bly such as volume.strain, angle.of friction, angle.of dilatancy and e.astic modulus is studie. during the.simulation te.ts both for non-bre.kable.and bre.kable.soil particle.. At the.e.d, a parame.ric study is pe.forme. on the.e.fe.t of stre.gth of particle.bre.kage.on the.asse.bly be.avior.
