FE Micromodel of a Cord-rubber Composite Test Specimen Subjected to Uniaxial Tension

The aim of this study is to examine displacements, strains and stresses as well predict possible failure mechanisms arising at the yarn-matrix level a test specimen railway composite cord-rubber air brake tube undergoing uniaxial tension by microscale modelling.Furthermore, paper also aims verify material properties micromodel specimen.The based on macromodels (by matching boundary conditions micromodels with displacements macromodels) created previously authors article. reinforcing yarns are described an orthotropic, elastic model, whereas matrix has been 2 parameter Mooney-Rivlin which all have validated before tensile three-point bending test.Force-displacement curves experimental results show considerably good agreement.Yarns less dominant role in load transfer mechanism reinforcement layers, because short-yarn reinforced nature specimen. Shear high free yarn ends marking locations initiation debonding shear layers. High strain values imply that mode
