An effective multilayered sandwich beam-link finite element for solution of the electro-thermo-structural problems

The first part of this contribution deals with deriving the effective matrices of the multilayered sandwich 2D-link/beam finite element made of FGM (functionally graded material) with variation of material properties and rectangular cross-section for solution of weak-coupled electric–thermal–structural problems. 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 second part of this contribution is completed by numerical validation, which documents the high accuracy and effectiveness of our proposed electro-thermo-structural composite (FGMs) link/beam finite element.
