Paper Title:
Hybrid Finite Element Formulation for Temperature Prediction in Carbon Nanofiber Based Composites
  Abstract

The temperature distribution in nanoscale cylindrical representative volume element (RVE) with centered carbon nanofiber (CNF) was modeled by the developed hybrid finite element approach, which used the axisymmetric Green’s function to approximate the interior field within the element, while the independent element boundary field with conventional shape functions was assumed to keep the continuity of field variables between adjacent elements. As a result, coupling with the constructed hybrid functional to link the independent interior and boundary fields, the solving linear system of equations with boundary integrals only were obtained. Numerical examples were given to show the accuracy of the proposed approach, and results were found in good agreement with those of ABAQUS. Also, it was obvious that the surface temperature of nanofiller almost kept constant during heat transfer, due to the large difference of thermal properties between nanofiller and matrix.
