In the formulation of the element two new rotations, which vary quadratically through the thickness, have been introduced. This provides a quadratic variation of the transverse shear strains, and a cubic variation of the displacements through the thickness.

WebLinear thick shell elements (QTS4) do not simulate the change in bending moment across a structure as well as linear thin shell elements (QSI4), quadratic thick shell elements (QTS8) or plate elements.
