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 assumes strains...

. To improve the displacement and stress responses, a proper mixed interpolation of the strain fields is propounded. Moreover, Mixed Interpolation of Tensorial Components (MITC) has been employed to alleviate in-plane shear locking. The advantage...
