للكاتب Omar Al-Hattamleh Department of Civil Engineering – Hashemite University – Jordan ABSTRACT: Localisation of deformation into narrow shear bands is a fundamental phenomenon in granular materials. Constitutive equations that do not consider the effect of higher order deformation gradients fail to predict deformation patterns that persist and eventually dominate shear bands. This paper presents a higher order gradient multi-slip …
