Abstract
In this study, an elastic-plastic stress analysis has been carried out in a thermoplasticcomposite cantilever beam. The thermoplastic composite beam was reinforced by steelwoven fibers. The beam was loaded uniformly. The orientation angles were chosen as0°, 15°, 30° and 45°. The finite element models of the beams were developed by usingANSYS software. The obtained results from the nonlinear analyses show that theresidual stress component of /sigma xis the highest at the fixed end at the upper and loweredges for the 0° orientation. However, it is the highest on or around the elastic plasticboundaries for the 15°, 30° and 45° orientations. The magnitude of the residual stresscomponent of /tau xyis found to be the highest at or around the axis of the beam at thefixed end. 30° orientation produces the highest stress component of /tau xyaround the axisof the beam. Also, it is found that the magnitude of the residual stress component of /sigma x is higher that that of the /tau xy.
