Abstract

This study presents a finite element model for the analysis of creep buckling of a functionally graded Al–SiC composite beam with continuously varying material properties. The creep behaviour is described using the Norton–Bailey creep law, with parameters obtained from experimental data and interpolated to represent material gradation. A one-dimensional spatial finite element formulation is employed to simulate nonlinear buckling behaviour and predict critical creep buckling times. The developed model is validated through comparison with a FEMAP shell model, showing good agreement in the obtained results. The influence of material gradation and loading conditions on creep response is also investigated. The results demonstrate that the proposed approach provides an efficient and reliable tool for analysing creep buckling in functionally graded composite structures.
