Static analysis of functionally graded plates using the high-order shear deformation theory by MITC3 plate elements having strains smoothed on edges

The paper presents an efficient 3-node triangular finite plate element for static
analysis of functionally graded plates using the high-order shear deformation theory
(HSDT). The strain fields of the plate elements, which use the MITC3 technique to
remove the shear-locking phenomenon, are smoothed on the edges of the elements to improve numerical demonstration. The proposed 0C -type plate elements, namely ESMITC3, need to two additional degrees of freedom at eachnode for solving functionally graded plates using the HSDT but shear correction factors of the plates are eliminated. The robustness and accuracy of the ES-MITC3 plate elements are evaluated by several numerical examples.
