In this study, an elastic-plastic stress analysis is carried out on symmetric steel fiber reinforced high density polyethylene thermoplastic matrix laminated beams under a bending moment. The Bernoulli-Euler theory is used. The orientation angles are chosen as (90o/0o)2, (30o/-30o)2, (45o/-45o)2 and (60o/-60o)2. The composite material is assumed to be linearly hardening. The stress component 'sigma'x is to be maximum at the upper and lower surfaces in the elastic-plastic solution. The residual stress component 'sigma'x is found to be highest at the upper and lower surfaces. However, when the plastic region is further expanded the residual stress component 'sigma'x is found to be the highest at the elastic and plastic boundaries. The plastic flow is to be maximum at the upper and lower surfaces for the (30o/-30o)2 orientation. The transverse displacement is obtained to be highest at the free end for the (90o/0o)2 orientation.
