Elasto-Plastic Stress Analysis of Thermoplastic Matrix Composite Laminated Plates Under In-Plane Loading

An elastic-plastic stress analysis and the expansion of plastic zone in layers of woven steel fiber-reinforced thermoplastic matrix-laminated plates are studied by using the Finite Element Method and the First-order shear deformation theory for small deformations. Composite structures consisting of woven Cr-Ni wire as a fiber and F2.12 low-density polyethylene as a thermoplastic matrix were manufactured by hot-press molding. The mechanical properties were experimentally determined. The effect of orientation angle and symmetric-antisymmetric structures were investigated. It is assumed that the laminated plates are subjected to in-plane uniform loads. Loading is gradually increased from yield point of the plate as 0.01 MPa at each load step. Load steps are chosen as 300, 400, and 500.

In this study, mechanical buckling behaviors of composite square plates of four symmetric and antisymmetric layers with holes are examined. A thermoplastic material is used as the matrix material. Two different reinforced materials are used, of which one is a galvanized steel wire and the other a woven galvanized wire. The hole type is taken as circular. The finite element method is used for the solution. First critical buckling loads of an orthotropic plate with and without hole subjected to unidirectional compression are found. The results are illustrated in figures.

“…Elasto-plastic stress analysis in metal-matrix plate loaded transversely [6] was studied by Sayman. The residual stresses for thermoplastic matrix composite laminated plates under in-plane loading are determined by Yapici et al [7] by using finite element technique. The expansion of plastic zone in metal-matrix laminated plates was studied by Atas [8].…”
