The problem of instability and strain localization in granular materials is approached using a modified Cam-clay plasticity model. The attention is limited to one-phase modeling based on the Terzaghi concept of effective stress. The gradient-enhancement of the model is proposed in order to avoid the spurious discretization sensitivity of finite element solutions. The classical and gradient-dependent versions of the theory and their numerical implementation are summarized. Basic one-element tests and a typical shear banding benchmark of biaxially compressed soil specimen are discussed. Calculations arc performed using the development version of the FEAP finite clement package.
