Elasto-plastic stress analysis of steel fibre reinforced aluminium metal matrix composite plates

This study consists of three stages. First of all, metal matrix compositestructure is obtained. Aluminium is used as matrix material and steel isused as fibre material in the composite structure. Steel fibres areuniaxially oriented on the matrix. Epoxy resin is used to form a boundbetween matrix and fibre. Composite structure is annealed in thefurnace at 80 oC for an hour to harden the resin. This manufacturingmethod is more simple than hot pressing. In this method, high affinityof aluminium to oxygen doesn?t cause a disadvantage. Afterwards,engineering constants and mechanical properties of the compositestructure is obtained with simple tension tests. Tensile strength of thecomposite material is increased with the increasing fibre ratio. Thetests show that resin has no contribution in the strength of compositematerial, but it is a very effective adhesive. Finally, elasto-plastic stressanalysis is realised with ANSYS packet program. In the study, elasto-plastic stress analysis is carried out for symmetric cross-ply (0/90 o)2and angle-ply (15/-15o)2, (30/-30 o)2, (45/-45 o)2, steel fibre reinforcedaluminium metal matrix composite laminated plates. The symmetricallaminated plates are simply supported from all its edges. Tsai-Hilltheory is used in the analysis for yield criterion. Furthermore, stress-strain diagrams of hot pressed composite material are presented in theappendix section.:Composite material, elasto-plastic stress analysis,epoxy resin, finite element method, ANSYS
