title: Pulling or compressing a vesicle by force: solution to the bending energy model.
abstract: The shape transformation induced by pulling or compressing a vesicle along the symmetric axis is discussed in light of the numerical solution to the bending energy model with fixed enclosing volume and surface area. A complete phase diagram in terms of the external force and reduced vesicle volume is investigated. Some experimental observations are explained by the solution.
