Which bending theory should I use for the calculation of plates and shells (Kirchhoff / Mindlin)?
In the calculation according to the Mindlin theory, shear force deformations are included, but are not considered according to the Kirchhoff theory.
If thicker plates and shell elements are calculated, the Mindlin theory results in more precise results. When calculating thin or very thin elements, the Kirchhoff theory is appropriate.
