In this study elastic - plastic stress analysis is examined in a laminated thermoplastic composite plates under transverse loading conditions. For solving problem ANSYS program,which is used finite element method, is used. The effect of ply array, fiber orientation angle, supported type and plate dimension variation on elastic - plastic and residual stresses of laminated thermoplastic composite plates are investigated. Elastic-plastic analysis is made three steps. In the first step of the analysis the yielding loads are finding each plate and in the second step elastic-plastic stresses are obtained from yield load + 0.01 MPa load increment for each plate. The last step is made for obtained residual stresses and the load on the plate is removed. Obtained elastic-plastic and residual stresses are illustrated graphs in this study.
