Abstract: Polymer/clay nanocomposites (PCNs) have drawn great attention both from industry and academia due to their remarkable enhancement of mechanical, thermal and barrier properties compared to traditional polymers. Although the elastic properties of PCNs have been extensively studied and well documented, their damage behavior has not yet been completely addressed. In this thesis, the damage behavior of two typical PCNs systems, namely the epoxy/clay nanocomposites (ECNs) and the nylon 6/clay nanocomposites (NCNs) were characterized by a 3D representative volume element (RVE) model implemented with the computational homogenization approach. This study suggests the 3D RVE model implemented with computational homogenization method and appropriate damage criteria could successfully replicate the properties of ECNs/NCNs. This method could be applied to other PCNs provided material properties of their constituents are well characterized.
