An elastic-plastic stress analysis has been carried out in a stainless steel fiber reinforced aluminum matrix composite beam. The beam is loaded by a single force at its free end. The composite material is assumed perfectly plastic to simplify the investigation. An exact solution is given for the elastic and elastic-plastic regions. Orientation angles of the fiber are chosen as 0 degrees, 30 degrees, 45 degrees, 60 degrees and 90 degrees. The plastic zone expands at the upper side of the beam more than at the lower side for 30 degrees, 45 degrees and 60 degrees orientation angles. Residual stress components of sigma (x) and tau (xy) are found in the sections of the beam. The plastic collapse occurs at the different points for the beam of 0 degrees, 30 degrees, 45 degrees, 60 degrees and 90 degrees orientation angles.
