Abstract
Presented is a mesomechanical model that simulates the behavior of loc alized plastic deformation in polycrystal subjected to uniaxial load. Edge effect and pore concentration are analyzed. Predicted results bet ween the mechanical properties of polycrystal and pore concentration a re inconclusive as porosity alone could not explain the increase or de crease of polycrystal strength. The model applies to low pore concentr ation of less than 5% and hence coalescence of pores is also neglected . (C) 1998 Elsevier Science Ltd. All rights reserved.
