Web2 apr. 2024 · Only in the limiting case of vanishing nematic ordering (κ 1, κ 2, κ 3 ≪ κ), the Canhham–Helfrich theory is recovered [7–9]. In order to test for the practical applicability of our theory with specific membrane shapes, the embedding function must be subjected to adequate 2D-parametrization that allows explicit calculations of the strain field variables.
