Abstract

Abstract

Firstly,a series of advance on effect of pore pressure on strain localization of solid has been introduced in this paper Secondly,the effect of pore pressure on strain localization(shear bands) of the rock has been modeled based upon fast Lagrangian analysis.The results modeled show that the pore pressure has an great influence on the strain localization;The increase of pore pressure prevents shear bands from developing fully and causes tension failure of rock sample.
