Critical void ratio:
- In case of loose sand (at high initial void ratio), as the shear strain is increased, the void ratio decreases from an initial large value and In case of dense sand (at very low initial void ratio), the initial void ratio increases after a slight initial decrease.
- At large value of shearing strain, both the initially loose and initially dense sands approach a constant value of void ratio (i.e. change of volume remains constant during shearing), called critical void ratio.
Important PointsPoint of contraflexure: It is the point in bending moment diagram of a structure at which bending moment changes sign.
Bulking: Increase in volume of sand due to apparent cohesion.
