| Research Abstract |
Particle breakage occurs in granular materials in various engineering applications such as driving of piles and debris flows, and its influence on mechanical behaviour of soils should be considered properly in a constitutive model for soils. The effect of particle breakage is to increase fine particles and to broaden the grading of particle sizes, and the primary effect of broadening the grading is to change the characteristics of the volumetric response. In the present study, an existing model, in which the critical state line plays a central role as a locus of asymptotic states, has been extended to include the effects of particle breakage.
