Title of talk: “Finite Element Solutions of Multi-directional Functionally Graded Structures”.
Abstract: The applicability of composite materials in various weight-sensitivity areas such as aerospace, automobile, defense, biomedical, sports, etc., have addressed by many engineers, technologists and researchers due to their tailor-made properties. Functionally graded materials (FGMs) are the advanced form of composites that exhibit an inhomogeneous character especially designed for the high-temperature applications such as aircraft engines, rocket heat shields, thermal barrier coatings, heat exchanger tubes, etc. This material has been developed by taking the gradual variation of metal and ceramic constituents in a very efficient manner to suit the needs of the engineering structure. The effective material properties of the FGM follow the rule-based grading of two counterparts as discussed above, metals and ceramics. The present study aims the comprehensive numerical assessment of multidirectional FGM panel structures with different material gradation patterns and degrees of material heterogeneity. For this purpose, the finite element solutions of multidirectional functionally graded composite panels subjected to uniform and sinusoidal transverse loads are presented under different support conditions. Here, different FGM composites, such as unidirectional (1D) and multidirectional (2D/3D), are considered by distributing constituent materials in one, two and three directions, respectively using single and multivariable power-law functions. A constitutive model with fully spatial-dependent elastic stiffness is developed, whereas the kinematics of the present structure is defined using equivalent single-layer higher-order theory. The weak form is established and solved consequently in 2D finite element platform. Further, the stability and correctness of the model have been confirmed through the appropriate numerical illustrations. The new numerical examples depict the importance of degree of material heterogeneity with different gradation patterns and volume-fraction exponents on the deformation behavior of multidirectional FGM panels under various loading and support conditions.
