DEVELOPMENT OF MATHEMATICAL MODEL FOR ANALYSIS OF CYLINDRICAL COMPONENTS MADE OF FUNCTIONALLY GRADED MATERIALS UNDER PRESSURE AND THERMO MECHANICAL LOADING
Keywords:
Thermo-mechanical loading, Multi-layered approach, Functionally graded circular hollow cylinderAbstract
The gradual linear variation in properties of the functionally graded circular hollow cylinder is assumed to be split up into multiple layers in the radial direction and each of which is individually isotropic in nature. The cylinder is assumed to be of finite length and is subjected to axisymmetric thermal and mechanical loads. The fundamental thermo-mechanical relationships obtained for the two-layer isotropic material is extended to the assumed concept of multiple layer isotropic material applicable to functionally graded material. The solutions for temperature, displacements, and thermal/mechanical stress distribution in a functionally graded circular hollow cylinder are presented in this paper. The mathematical model which is developed can be used to analyze functionally graded circular hollow cylinder.
