Popis: In the present study, the normal and interfacial shear stress distributions of short fiber composites under a force parallel to the fiber direction are investigated by using the global-local finite element method. A finite element analytical procedure will be developed by combining the hybrid stress finite element method and the conventional displacement-based plane stress element to predict the normal and interfacial shear stress of short fiber composites. The effects of different geometrical shapes of fiber end, the ratio of fiber length to diameter, the fiber volume fraction and the elastic modulus ratio to the normal stress and the interfacial shear stress distributions of short fiber composites will also be conducted. The geometrical shapes of fiber end under present investigation are blunt, V-shaped, wedge-shaped and semi-circular, respectively.
