Abstract

In this study an elastic-plastic stress analysis is carried out in a woven steel fiber reinforced thermoplastic composite cantilever beam loaded by a constant single force at its free end. The expansion of the plastic region and the residual stress compenent of ?x are determined 0, 15, 30 and 45 orientation angles. Yielding begins for 0 and 45 orientation angles both of upper and lower surfaces of the beam at the same distances from the free end. An elastic-plastic analysis is carried out for the plastic region which spreads at the upper and lower surfaces together. The residual stress compenents are obtained after releasing the external force. The distributions of the residual stress compenents of ?x are also determined. The intensity of the residual stress compenents of ?x is maximum at the upper or lower surfaces of the beam
