Large deformation analysis of laminated composite structures by a continuum-based shell element with transverse deformation
… is approximated through the thickness by a quartic polynomial of the thickness coordinate. As a result both the plate/shell surface tractions (including nonzero tangential tractions and nonzero normal pressure) and the interlaminar shear stress continuity conditions at interfaces are …

Theoretical Investigation of the Structure and Vibrational Frequencies of Water and Methanol Complexes
… mode. A second new method is based on fitting a quartic polynomial to energies computed along each normal mode. In cases where the quartic potential function is not very different from the harmonic well, a second order perturbation formula provides a reasonable approximation to the anharmonic …
