Shallow shell theory of the buckling energy barrier: from the Pogorelov state to softening and imperfection sensitivity close to the buckling pressure
Lorenz Baumgarten, Jan Kierfeld
We study the axisymmetric response of a complete spherical shell under homogeneous compressive pressure to an additional point force. For a pressure below the classical cri…
Elastic capsules at liquid-liquid interfaces
Jonas Hegemann, Horst-Holger Boltz, Jan Kierfeld
We investigate the deformation of elastic microcapsules adsorbed at liquid-liquid interfaces. An initially spherical elastic capsule at a liquid-liquid interface undergoes circumfe…
Buckling of thermally fluctuating spherical shells: Parameter renormalization and thermally activated barrier crossing
Lorenz Baumgarten, Jan Kierfeld
We study the influence of thermal fluctuations on the buckling behavior of thin elastic capsules with spherical rest shape. Thermal fluctuations affect the buckling instability by…
Spheroidal and conical shapes of ferrofluid-filled capsules in magnetic fields
Christian Wischnewski, Jan Kierfeld
We investigate the deformation of soft spherical elastic capsules filled with a ferrofluid in external uniform magnetic fields at fixed volume by a combination of numerical and ana…
