Abstract

Abstract: Nanocomposites exhibit excellent fracture toughness due to adding nanoparticles into the polymer matrix. The present work aims at developing a multiscale modelling approach to investigate fracture behaviour of nanocomposites with core‐shell nanostructures. In this context, a nonlocal damage model based on the micropolar theory is proposed to describe the damage behaviour of graded shell layers of nanoparticles. The simulation results show the capability of the present model to study the effect of shell morphology and shell material on the fracture toughness of nanocomposites within this multiscale simulation framework.
