Abstract:
This paper focuses on secondary creep analysis in functionally graded (FG) rotating cylinders subjected to internal and external pressure. For a prolonged period of time, when the material undergoes a steady magnitude of load, it experiences a time-dependent deformation that is irreversible and known as a creep deformation. This paper analyses secondary creep stresses and strains in functionally graded cylinders with different volume reinforcement profiles and different material combinations. An anisotropic cylinder with varying nonlinear volume reinforcement of the ceramic in the metal matrix is considered and closed form results are obtained for the creep stresses and creep strains in the radial and tangential directions. The results are plotted graphically, and the implications of the results are discussed using the numerical values over the radial dimension of the functionally graded cylinder.
