Abstract
In this study, an elastic-plastic stress analysis was carried out in woven steelfibers- thermoplastic clamped composite laminates. The stacking sequences werechosen as [0/0]2, [15/-15]2, [30/-30]2 and [45/-45]2 for woven steel fibers –thermoplastic composites plates. The layers were chosen for symmetric andantisymmetric cases.The finite element solution was performed by using the ANSYS software. Solid186 element was utilized in the solution. Normal stress components at the clampededges were found to be higher than that at the mid point of the laminated plates. Normalstresses are tensile at the mid point of the clamped edges and compressive at the midpoint of the laminated plates. Then, the residual stress components were calculated inthe critical points of the composite laminates.
