Abstract

A novel method for analyzing tubular composites was developed by obtaining a curved representative volume element (RVE) from the transformation of a flat RVE. There was found to be a discrepancy in the stress between the two RVE models of approximately 15%. The curved RVE model was validated using an isotropic material.
