New higher-order triangular shell finite elements based on the partition of unity

PU approximation with the Finite Element Method is effective for p-adaptivity and smooth solutions without domain remeshing. PU has eliminated transverse shear locking and improved convergence and accuracy. However, its increased degrees of freedom make it impractical for engineering. We propose a new method using mixed interpolation of tensorial components to reduce computational costs without affecting accuracy. The proposed shell element has been tested in three benchmark problems and has been shown to be effective.
