An Effective Multiphysical Functionally Graded Material Beam-Link Finite Element with Transversal Symmetric and Longitudinal Continuous Variation of Material Properties

摘要

The theoretical part of this contribution deals with deriving the effective matrices of the electric-thermal-structural 2D-link/beam finite element with a constant cross-section (which is predominantly rectangular) with variation of the effective material properties. This 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 theoretical part of this contribution is completed by numerical validation, which documents the high accuracy and effectiveness of our proposed multiphysical composite (FGMs) link/beam finite element.
