In this paper, two new quadrilateral elements are formulated to solve plane problems. Low sensitivity to geometric distortion, no parasitic shear error, rotational invariance, and satisfying the Felippa pure bending test ...

The strain formulation approach improves accuracy and removes complications, such as, shear
parasitic errors and sensitivity to mesh distortions. For analyzing plane stress and strain problems,
two new strain-based ...

A new higher-order triangular plane element with drilling degrees of freedom is proposed by assumption of second-order strain field. In addition to inclusion of drilling degrees of freedom and utilization of higher-order ...

Two new elements with six degrees of freedom are proposed by applying the equilibrium conditions and strain-displacement equations. The first element is formulated for the infinite ratio of beam radius to thickness. In the second one, theory...
