Paper Title
An Edge-based Smoothed Finite Element Method with DSG3 Element for Analysis of Functionally Graded Plates
Abstract
The convergence behavior of the Edge-based Smoothed Finite Element Method (ES-FEM) with a triangular
Discrete Shear Gap (DSG3) element in analyzing the Functionally Graded Material (FGM) plates will be studied in this
paper. FGM consists of at least two materials whose volume fractions continuously change along with the thickness of the
material. ES-FEM will be applied to the DSG3 element to enhance its accuracy, in analyzing displacement in this case. ESDSG3
will be formulated and demonstrated on the square FGM plate static problem to show the convergence behavior. Two
additional degrees of freedom on each node is introduced as a consequence of the membrane-bending coupling effect of
FGM. The constant strain matrix along the element makes the computational process running relatively faster than other
elements.
