Abstract

A representative volume element (RVE) involving a single carbon nanotube (CNT) embedded in a plastic matrix is used to model the elastic behavior of the nanocomposite using finite elements. When the RVE is loaded axially, the maximum shear stress at the CNT-matrix interface can exceed the interfacial shear strength causing slippage of the CNT inside the matrix. Cyclic loading causes hysteretic stress-strain behavior of the nanocomposite and dependencies on the interfacial strength, geometry, relative elastic properties of the CNT and the matrix, and volume fraction of the CNTs are investigated.
