Özet
The nonlinear stress analysis and the spread of plastic zones in layered woven steel fiber-reinforced thermoplastic-matrix laminated rectangular plates are examined using the Finite element method and the first-order shear deformation theory for small deformations. Composite structures consisting of woven Cr-Ni wire as the fiber and F2.12 low-density polyethylene as the thermoplastic matrix are manufactured by hot-press molding. The mechanical properties are experimentally determined. The effect of aspect ratio of rectangular plate and antisymmetric structure is investigated. It is assumed that the laminated plates are subjected to in-plane uniform loads. Loading is gradually increased from the yield point of the plate as 0.01 MPa at each load step. Load steps are chosen as 300, 350, and 400 iterations. Residual stresses and expansion of plastic zone have been presented by means of tables and figures.
