Response in nonlinear thermal stress assessment of a 2D-FG short axisymmetric cylinder

Purpose We conducted transient thermal stress assessment of a 2D-FG short axisymmetric cylinder. Design/methodology/approach The higher-order finite element analysis of nonlinear thermo-elastic response on a two-dimensional functionally graded (2D-FG) short axisymmetric cylinder, incorporating temperature-dependent (TD) material properties and the Mori–Tanaka scheme has been utilized. Findings When taking into account TD and TID, the coefficient of thermal expansion (CTE) combined with temperature differences on the inner surface plays an important role in formative thermal stresses. Neglecting temperature dependency results in substantial discrepancies in thermal stress levels. Originality/value Our research focuses on temperature, displacements, thermal stresses and Drucker–Prager (D-P) stress to determine the effect of material gradation, temperature dependency and cylinder strength under severe thermal loading.
