Representative volume element based micromechanical modelling of rod shaped glass filled epoxy composites

Abstract In this study, Representative Volume Element based micromechanical modeling technique has been implemented to assess the mechanical properties of glass filled epoxy composites. Rod shaped fillers having an aspect ratio 80 were used for preparing composite. The three-dimensional unit cell model representative volume element was prepared with finite analysis tool ANSYS 19 using periodic square and hexagonal array assumption that there is a perfect bonding between filler matrix. Results revealed tensile modulus increases Poisson’s decreases increase in fraction filler. To study effect fraction, pulse echo techniques experimentally measure 5% 15% A good agreement found RVE predicted values experimental results.
