Finite element prediction of stress transfer in h-BN sheet nanocomposites

Abstract

PurposeThe purpose of this paper is to implement a micromechanical hybrid finite element approach in order to investigate the stress transfer behavior of composites reinforced with hexagonal boron nitride (h-BN) nanosheets.Design/methodology/approachFor the analysis of the problem, a three-dimensional representative volume element, consisting of three phases, has been used. The reinforcement is modeled discretely using spring elements of specific stiffness while the matrix material is modeled as a continuum medium using solid finite elements. The third phase, the intermediate one, known as the interface, has been simulated by appropriate stiffness variations which define a heterogeneous region affecting the stress transfer characteristics of the nanocomposite.FindingsThe results show a good agreement with corresponding ones from the literature and also the effect of a number of factors is indicated in stress transfer efficiency.Originality/valueThis is the first time that such a modeling is employed in the stress transfer examination of h-BN nanocomposites.
