Elastoplastic stress analysis of functionally graded disc under internal pressure-complas XII.9788494153150https://hdl.handle.net/11491/210212th International Conference on Computational Plasticity: Fundamentals and Applications, COMPLAS 2013, 3 September 2013 through 5 September 2013, BarcelonaThe study deals with elastoplastic stress analysis of a hollow disk made of functionally graded materials (FGMs) subjected to an internal pressure. The material properties of disc are assumed to vary radially according to power law function, but Poisson's ratio is taken constant. Small deformations and a state of plane stress are presumed, and the analysis of disk is based on Von-Mises yield criterion. The materials are assumed to be linear strain hardening, isotropic and not be affected by temperature. Variation of stresses and displacements according to gradient parameters are investigated by using analytical and finite element method. The results show that gradient parameters have an important role in determining the elastoplastic stress of functionally graded disc.eninfo:eu-repo/semantics/closedAccessElastoplastic StressFinite Element MethodFunctionally Graded DiskLinear Strain HardeningResidual StressConference Object823831N/AN/A
