Numerical elastic plastic stress analysis in a woven steel reinforced composite thermoplastic cantilever beam

Abstract

In this study, an elastic-plastic stress analysis has been carried out in a thermoplastic composite cantilever beam. The thermoplastic composite beam was reinforced by steel woven fibers. The beam was loaded uniformly. The orientation angles were chosen as 0°, 15°, 30° and 45°. The finite element models of the beams were developed by using ANSYS software. The obtained results from the nonlinear analyses show that the residual stress component of ? x is the highest at the fixed end at the upper and lower edges for the 0° orientation. However, it is the highest on or around the elastic plastic boundaries for the 15°, 30° and 45° orientations. The magnitude of the residual stress component of ? xy is found to be the highest at or around the axis of the beam at the fixed end. 30° orientation produces the highest stress component of ? xy around the axis of the beam. Also, it is found that the magnitude of the residual stress component of ? x is higher that that of the ? xy.
