Abstract

Abstract: A formulation of a three-dimensional homogenized constitutive model is developed that can predict strain localization in fibre-reinforced composites. A constitutive equation for the model is developed in a general rate form based on independent constituent behaviour which can be either elastic or elastic-plastic. The performance of the constitutive model is investigated by performing an infinite kink band analysis. The development of a kink band is investigated for several initial imperfections and compared with previously published results.
