Effect of strength anisotropy on strain localization in natural clay

Strain localization in soils causes the failure of slopes and foundations. Shear strength is an important factor that affects strain localization in soils. It is well known that the shear strength of natural clay is highly anisotropic due to the internal soil structure. An anisotropic failure criterion for natural clay is presented in which an anisotropic variable is used to describe the relative orientation between the stress directions and …
