Keywords: short fibre composites, shear lag theory, creep, analytical modeling, fem

A new analytical model based on the shear-lag theory is developed for stress analysis and steady state creep deformation of short fiber composites subjected to an applied axial load. The analytical results are validated by FEM modeling and good agreements are found between the calculated stress, and strain rate components.
