Correction:you can bend a single linear shell element without any nodal displacement by just rotating the nodes at each end is not correct.nYou can bend a single linear

**beam**element without any nodal displacement by just rotating the nodes at each end. The shape function in a beam element is quadratic. The shape function in a linear shell element is linear so you get no internal displacement in the element from applied rotation.nYou can bend a single**quadratic**shell element by just rotating the nodes at each end because the element has a quadratic shape function. There is also a midside node which would translate.n
