“…When compared to isotropic materials, an FG cylinder has a larger energy absorption capacity (Bacciocchi et al, 2019;Menasria et al, 2020). A non-linear finite element approach was employed to study buckling in a cylindrical panel for several lamination arrangements and BC's (boundary conditions) (Liang and Li, 2022). The pressure-bearing capability of shells under blast loading was solved using Lame's approach (Chen et al, 2021).…”

PurposeThe purpose of this study was to perform thermo-mechanical deformation and stress analysis in a functionally graded (FG) hollow cylinder considering steady-state temperature distribution under the effect of rotation, gravity and constant heat generation.Design/methodology/approachNavier's equation was used to solve the problem, and the obtained results were validated with benchmarks found to be in excellent agreement. The variation of temperature and other material properties such as Young's modulus, density, thermal expansion coefficient and thermal conductivity varied radially as per power-law variation.FindingsThe effect of rotation was found to be vital compared to gravity and heat generation when compared individually and in combination. The results of displacement and stresses were presented for varying grading indices.Practical implicationsFG cylinders have huge industrial applications as it opens the possibility of developing structures with a high strength/weight ratio. The present study will benefit industries in identifying the effective grading index that can be used by industries for fabricating FG structures.Originality/valueThe effect of rotation, body force and heat generation on a cylindrical body has not been studied before. Furthermore, the combined effect of rotation, body force and heat generation has been studied to understand the behaviour of cylinders operating under similar conditions.

In the present study, one-dimensional steady-state temperature variation with variable heat generation was considered and thermo-mechanical stress and deformation analysis on a hollow functionally graded cylinder were then performed. A governing differential equation with a variable coefficient is solved using Navier's equation by applying thermal and mechanical boundary conditions. The effect of internal pressure and temperature, rotation, gravity, and heat generation, and their combined effect such as rotation and heat generation, gravity and heat generation, rotation, gravity, and heat generation were studied in a cylindrical body. The gradation properties varied radially as per power-law variation. The grading parameter ranging between -2 to 3, changes the material properties in the radial direction. A critical grading index was identified that lowers the induced stresses and hence an improvement in the performance of functionally graded cylinders can be obtained under the influence of a combination of loads. The validation of the results was carried out with published literature.
