“…The modelling of FGMs is important because the effective estimation of material properties defines the accuracy with which the solution of different engineering analysis such as stress analysis (Madan and Bhowmick, 2021), buckling (Bakoura et al, 2021;Daikh, 2020;Javaheri and Eslami, 2002;Yang et al, 2021), bending analysis (Arefi and Zenkour, 2017;Arshid et al, 2021;Bellifa et al, 2016;Karamanlı, 2017), free vibration (Bacciocchi et al, 2019;Chen et al, 2016a;Garg et al, 2022;Iurlaro et al, 2015) and for a combination of loads (Arefi and Zenkour, 2017;Behravan Rad and Shariyat, 2016;Zenkour, 2014). Out of several available models rule of mixture, modified rule of mixture, Mori-Tanaka and Halpin-Tsai method are widely used (Madan and Bhowmick, 2022).…”

PurposeIn this work, the effect of porosity volume fraction, porosity types, material grading index, variable disk profiles and aspect ratio on disk performance was studied by performing limit elastic speed analysis of functionally graded porous rotating disks (PFGM) under thermo-mechanical loading.Design/methodology/approachThe composition change was varied by employing the power law function. The thermo-mechanical properties of PFGM such as Young's modulus and yield strength were estimated using modified rule of mixture, for density and coefficient of thermal expansion rule of mixture was used. The even and uneven distribution of porosity in a disk was taken as uniform, symmetrical, inner maximum and outer maximum. The problem was then solved with the help of the variational principle and Galerkin's error minimization theory.FindingsThe research reveals that the grading parameter, disk geometry and porosity distribution have a significant impact on the limit elastic speed in comparison to the aspect ratio.Practical implicationsThe study determines a range of operable speeds for porous and non-porous disk profiles that the industry can utilize to estimate structural performance.Originality/valueA finite element investigation was conducted to validate the findings of the present study. Limit elastic analysis of porous FG disks under thermo-mechanical loading has not been studied before.
