Abstract：We consider the system of two immiscible fluids on an elastic membrane, where the fluid interface intersects with the membrane at a contact line. We first study the static profiles of the interfaces by minimising the total energy of the system, which consists of the interfacial energies and the membrane bending energy. Asymptotic solutions are obtained in the limits as the bending modulus tends to infinity (stiff limit) and zero (soft limit), respectively. We also consider the dynamical problem and derive the hydrodynamic model, particularly the boundary conditions, from generalised thermodynamics. Numerical solutions are presented for the relaxation of droplets on a membrane and transport of droplets by bendotaxis.
