Abstract: In this study, residual stress variations and expansion of plastic zone of woven steel fiber reinforced laminated thermoplastic composite plates with central elliptical hole which is subjected to in-plane loading are investigated for different loads. Numerical simulation is performed using a commercial packet programme ANSYS. To investigate the effects of orientation angle of elliptical hole in the composite laminated plate under various in-plane loads, elliptical hole is rotated from 0º to 90º by 15º increments counterclockwise. The in-plane loads are chosen as 5.5 MPa, 6.0 MPa and 6.5 MPa. Laminated plates are composed of [0/±30/±45/90]₂ fiber orientation in symmetric and antisymmetric manner.
