Özet
In this study, a residual stress analysis is carried out on symmetric cross-ply and angle-ply thermoplastic simple supported and clamped supported laminated plates for transverse loading. Low density polyethylene thermoplastic matrix (LDPE) and woven NiCr fibers are used to produce the composite plates by using molds. First order shear deformation theory and nine nodes Lagrangian finite element are used. Mathematical formulation is given for the elasto-plastic stress analysis of a laminated plate for small deformations. Yield points and stresses are obtained for symmetric simple supported and clamped supported laminated plates. Residual stresses in thermoplastic plates are given in the tables. The expansion of plastic zones is illustrated for 50, 100 and 150 loading steps. Yield points and the expansion of plastic zones are compared for different plates. Mechanical properties of a layer are obtained experimentally. © 2007 SAGE Publications.
