A new model is presented for analyzing the stress concentration of
unidirectionally reinforced fiber composite. The present model is based on variational
theory. The stress components are derived in terms of a perturbation function. A
parametric study of stress concentration factor (SCF) of the unidirectionally
reinforced fiber composite is carried out. In order to validate the present model, the
numerical results from the present work compare with those obtained from the shear
lag model. There is a good agreement between the results obtained by the two models.
