effects of hardening parameter and strain hardening exponent on residual stress and plastic zone growth in Aluminum Metal matrix composites under out of plane loading
Journal of Reinforced Plastics and Composites, 2004Co-Authors: Hasan Yildiz, Onur Sayman, Mehmet AktasAbstract:Residual stress variations and plastic zone growth behavior of steel fiber-reinforced Aluminum Metal-matrix laminated composite plates which are clamped and subjected to out-of-plane loading are investigated for different hardening parameter (K) and strain hardening exponent (n). Laminated plates are composed of four orthotropic layers oriented with different angles in symmetric or antisymmetric manner. The plates are meshed into 64 elements and 289 nodes with clamped boundary condition. Laminates are subjected to a transverse uniform distributed load. The loading is gradually increased after yield point of the plate to the higher levels with 400, 500, and 600 loading steps. Numerical solution is performed using the finite element method and the first-order shear deformation theory. For solution, Lagrange elements with nine nodes are used.

thermal residual stresses in Aluminum Metal matrix antisymmetric laminated plates under uniform temperature distribution
Journal of Reinforced Plastics and Composites, 2003Co-Authors: Onur Sayman, Cinar E Yeni, Evren M Toygar, Mehmet şenelAbstract:Thermal stresses are of great importance in composite structures. In this investigation, a thermal elastic-plastic stress analysis is carried out in (0°/90°) 2 , (30°/-30°) 2 , (45°/-45°) 2 , (60°/-60°) 2 , (15°/15°) 2 , (15°/30°) 2 , (15°/45°) 2 , (15°/60°) 2 antisymmetric Aluminum Metal-matrix laminated plates. Temperature is chosen to be constant along the cross sections of the plates. The residual stress components of σ x , σ v and τ xy are illustrated in the layers of the laminated plates for different thermal loading. Elastic-plastic and residual stress components are given in tables. When the absolute value between the orientation angles of the layers is increased, the magnitude of the residual stress components becomes high. The strength of the laminated plates can be increased by using residual stresses. Tsai-Hill criterion is used as a yield criterion. Differential equations are solved numerically with a sufficiently large number of integration intervals of the temperature. The composite material is assumed to be linearly strain hardening.

elastic plastic stress analysis of simply supported and clamped Aluminum Metal matrix laminated plates with a hole
Composite Structures, 2001Co-Authors: Onur Sayman, Sami AksoyAbstract:Abstract In this study, an elastic–plastic stress analysis is carried out on simply supported and clamped cross-ply and angle-ply Aluminum Metal-matrix composite laminated plates with a circular hole. Classical lamination theory with first-order shear deformation theory is used for small deformations. The expansion of the plastic region and residual stress components are obtained on the upper and lower surfaces of the plates by using the finite element method. They are loaded on the upper surface transversely. Loading is gradually increased from the yield point of the plate by 0.0001 MPa at each load step. Load step numbers are chosen as 400, 600 and 800.

elastic plastic stress analysis and expansion of plastic zone in clamped and simply supported Aluminum Metal matrix laminated plates
Composite Structures, 2000Co-Authors: Cesim Atas, Onur SaymanAbstract:Abstract An elastic–plastic stress analysis and the expansion of plastic zone in layers of stainless steel fiber-reinforced Aluminum Metal–matrix laminated plates are studied by using Finite Element Method and First-order shear deformation theory for small deformations. The plate is meshed into 64 elements and 289 nodes with simply supported or clamped boundary conditions. Laminated plates of constant thickness are formed by stacking four layers bonded symmetrically or antisymmetrically. It is assumed that the laminated plates are subjected to transverse uniform loads. Loading is gradually increased from yield point of the plate as 0.0001 MPa at each load step. Load steps are chosen as 100, 150 and 200.

investigation on diffusion bonding characteristics of Aluminum Metal matrix composites al sicp with pure Aluminum for different heat treatments
Journal of Materials Processing Technology, 2006Co-Authors: M Muratoglu, Okkes Yilmaz, Murat AksoyAbstract:Abstract Joining characteristic of SiC particulate reinforced Aluminum Metal matrix composites (MMCs) with pure Aluminum were investigated by diffusion bonding process. The joining quality of the Al/SiCp MMCs was studied to determine the influences of SiCp particulates with homogenization and age hardening on bonding properties. The experimental results indicate that the application of aging before and after diffusion bonding decreases SiC particulate accumulation, and increases other elemental concentration at interface. Especially, the application of aging treatment before the diffusion bonding of Al/SiCp MMCs to pure Al, increased Cu% concentration at interface which treats as the insert alloy.

application of response surface methodology for determining cutting force model in turning of lm6 sicp Metal matrix composite
Measurement, 2014Co-Authors: H Joardar, Goutam Sutradhar, N S Das, S SinghAbstract:Abstract In the present investigation an attempt is made to evaluate the effect of certain cutting variables on cutting forces in straight turning of Aluminum Metal matrix composites under dry cutting condition. Cutting speed, depth of cut and weight percentage of SiCP are selected as the influencing parameters. The application of response surface methodology and face centered composite design for modeling, optimization, and an analysis of the influences of dominant cutting parameters on tangential cutting force, axial cutting force and radial cutting force of Aluminum Metal matrix composites produced through stir casting route. Experiments are carried out using Aluminum (LM6) alloy reinforced with silicon carbide particles. The mathematical models are developed and tested for adequacy using analysis of variance and other adequacy measures using the developed models. The predicted values and measured values are fairly close, which indicate that the developed models can be effectively used to predict the responses in the turning of Aluminum Metal matrix composites. The contour plots of the process parameters revel that the low cutting forces are associated with the lowest level of depth of cut and the highest level of cutting speed and the sensitivity analysis revealed that cutting speed is most significant factor influencing the response variables investigated.

Experimental Investigation on the Effect of Reinforcement Particles on the Forgeability and the Mechanical Properties of Aluminum Metal Matrix Composites
Materials Sciences and Applications, 2010Co-Authors: Ramesh Behera, B. Oraon, Animesh Datta, G Majumdar, Goutam SutradharAbstract:The wide choice of materials, today's engineers are posed with a big challenge for the right selection of a material and as well as the right selection of a manufacturing process for an application. Aluminium Metal Matrix Composites is a relatively new material among all the engineering materials. It has proved its position in automobile, aerospace, and many other engineering applications due its wear resistance properties and due to its substantial hardness. One of the most important criteria is forgeability by which the workability of the material can be determined. The nature of distri-bution of reinforcing phase in the matrix greatly influenced the properties of Aluminum Metal Matrix Composites. The forgeability of Aluminum Metal Matrix Composites, which are produced by powder Metallurgy method, are greatly depends on the size and percentage of reinforcement materials, compacting load, sintering temperature and soaking time etc. In this present work, the forgeability of Aluminum Metal Matrix Composites reinforced with silicon carbide (400 meshes) has investigated. A comparison have been made with different types of Aluminum Silicon Carbide Metal Matrix Composite materials contains 0%5%,10%,15%&20% by weight of silicon carbide. The mechanical properties like hardness of the different composites have also investigated. It is observed that the forgeabilty of the composites decreases with increasing the wt% of SiC but the mechanical properties like hardness enhanced on increasing the wt% of SiC.
