Lecture-05 on shear strength of soil (c and phi, cohesion=c, angle of internal friction=phi)

In the shear strength of soil (c and phi), topics are covered:
01. Shear strength of soil (c and phi, cohesion=c, angle of internal friction=phi)
02. Mohr-Columb failure
03. Direct shear test (for sand)(c=0)
04. Triaxial test (for silt and clay) (CD, CU, UU)
05. Consolidated drain(CD), Consolidated un-drain(CU) and un-consolidated drain(UU) tests.
06. Cell pressure (sigma-3), deviator stress (delta-sigma), principal stress(sigma-3), minor stress(sigma-1)
