WebExtract of sample "Critical State Soil Mechanics". The soil attains a critical state when there is a constant shear stress and no further volumetric strain occurs. However, dry soils often attain peak shear stress before attaining the critical state. Hence, the strength of the soil is based on its critical state strength and the peak strength. Webcritical state soil mechanics (15 marks) 2. A sample of clay (Sample A) is isotropically normally consolidated to p'o = po = 400 kPa and vo = 2.052 and a second sample (Sample B) is isotropically consolidated to 863 kPa and allowed to swell to p'ı = pi = 40 kPa, when the specific volume is vo = 2.052.
