Stress-dilatancy Relation for Mohr-Coulomb Soils Following a Non-Associated Flow Rule

摘要: Rowe's stress–dilatancy relation for frictional (cohesionless) materials has been a cornerstone of soil mechanics. The original derivation this relationship was based on incorrect energy minimisation considerations, but the proven later by De Josselin de Jong using friction laws, and confirmed large body experimental results. In contrast, validity cohesive-frictional materials, which also used, although not as extensively, never verified. This paper shows that Mohr–Coulomb soils (cohesive-frictional materials) is in fact incorrect. provides correct non-associated have both cohesive strength components. presented relies use sawtooth model together with application laws friction.
