Abstract
The instability of the strain gradient-dependent elastoviscoplastic constitutive model for water saturated clay is studied in relation to the strain localization phenomena and pattern formation during deformation. The second-order gradient of volumetric viscoplastic strain is introduced into the constitutive equations to account for the non-local effects associated with the motion of microstructures. Boundary value problems by using finite element are formulated and strain localization analyses are carried out. © 1999 Elsevier Science S.A.
