Residual stress analysis is carried out in a thermoplastic composite laminated plate for in-plane loading. Low density polyethylene thermoplastic matrix (LDPE) and steel fibers are used to produce the composite plates by using moulds. The first order shear deformation theory and nine node Lagrangian finite element are used. Mathematical formulation is given for the residual stress analysis of a laminated plate for small deformations. Yield points and stresses are obtained for symmetric and antisymmetric laminated plates without and with a circular hole. Elastic, elasto-plastic and residual stresses in plates are given in tables. The expansion of plastic zones is illustrated for 100, 200 and 300 load steps. Yield points and the expansion of plastic zones are compared for different plates without and with a circular hole.
