Thermo-Elastic Stress Calculation in Multilayered FGM Sandwich Beams

Abstract eng:
This contribution deals with deriving the effective matrices of the linear-elastic composite multilayered sandwich beam finite element with a constant cross-section (which is predominantly rectangular) with variation of the effective material properties. The variation of effective material properties is caused by both continuous longitudinal and layer-wise symmetric transversal variation of the constituent’s volume fractions and constituent’s material properties. The structural and longitudinal varying temperature loads have been assumed. Expressions are presented for calculation of thermo-elastic deformation and stresses in homogenized beam and in the layers. Numerical validation documents the high accuracy and effectiveness of our proposed thermo-structural composite (FGMs) beam finite element.
