Finite Element Modeling and Experimental Validation of SiCp/Al2O3 Ceramic Matrix Composites Prepared by Directed Metal Oxidation of an Al Alloy M. Devaiah 1Department of Mechanical Engineering, Geethanjali College of Engineering & Technology, Cheeryal (V), Keesara (M), Medchal Dist. 501301, Telangana, INDIA. Corresponding, Mobile No.:+91-9948606326 ABSTRACT In this study, SiCp/Al2O3 ceramic matrix composite specimen of dimensions measuring 70 × 70 × 20, in mm with varying volume fractions in the range of 0.35 to 0.43. The purpose of this paper is to compare experimental results of SiCp/Al2O3 composites such as mechanical and physical properties of SiCp/Al2O3 composites with Mathematical models predictions. The Finite Element Method (FEM) is used for studying some of the problems. With the advancement of computers, finite element has become one of the most important tools available to an engineer for design. The finite element method is one of the most general procedures for solving complex analysis problems. For performing finite element analysis the material is considered to be isotropic in nature and the boundary conditions and load conditions applied are similar to those obtained in the experiments. In the present paper, different FEM models was created by using FEM software package ANSYS and found the nodal solution through FEM analysis for different mechanical and physical properties such as flexural strength, fracture toughness, compressive strength, coefficient of thermal expansion, modulus of elasticity of SiCp/Al2O3 composites with different volume fractions of SiC in the range of 0.35 to 0.43 and compared the FEM results with experimental results of as prepared SiCp/Al2O3 composites with different volume fractions of SiC. Keywords: Ceramic Matrix Composites, Al2O3, SiC, FEM, Mechanical and Physical Properties.
