Shear Strength of Soils and Failure Criteria

The problems solved in this chapter describe the shear strength characteristics of soils and related failure criteria . Problems 4.1 to 4.3 show the applications of the stress transformation equations in soils. The shear strength parameters , which include cohesion and internal friction angle, are investigated through Problems 4.4 to 4.9. Both, the effective stress analysis and the total stress analysis, are applied. The post peak behaviour of the soil may be predicted by using the critical state models that are now common for specific types of soils. The practical applications of the critical state theory are described by Problems 4.10 to 4.12.
