Pendant Capsule Elastometry
Jonas Hegemann, Sebastian Knoche, Simon Egger +5
We provide a C/C++ software for the shape analysis of deflated elastic capsules in a pendant capsule geometry, which is based on an elastic description of the capsule material as a…
Elasticity of Interfacial Rafts of Hard Particles with Soft Shells
Sebastian Knoche, Jan Kierfeld
We study an elasticity model for compressed protein monolayers or particle rafts at a liquid interface. Based on the microscopic view of hard-core particles with soft shells, a bea…
Osmotic buckling of spherical capsules
Sebastian Knoche, Jan Kierfeld
We study the buckling of elastic spherical shells under osmotic pressure with the osmolyte concentration of the exterior solution as control parameter. We compare our results for t…
The secondary buckling transition: wrinkling of buckled spherical shells
Sebastian Knoche, Jan Kierfeld
We theoretically explain the complete sequence of shapes of deflated spherical shells. Decreasing the volume, the shell remains spherical initially, then undergoes the classical bu…
Secondary polygonal instability of buckled spherical shells
Sebastian Knoche, Jan Kierfeld
When a spherical elastic capsule is deflated, it first buckles axisymmetrically and subsequently loses its axisymmetry in a secondary instability, where the dimple acquires a polyg…
Elastometry of Deflated Capsules: Elastic Moduli from Shape and Wrinkle Analysis
Sebastian Knoche, Dominic Vella, Elodie Aumaitre +4
Elastic capsules, prepared from droplets or bubbles attached to a capillary (as in a pendant drop tensiometer), can be deflated by suction through the capillary. We study this defl…
Buckling of Spherical Capsules
Sebastian Knoche, Jan Kierfeld
We investigate buckling of soft elastic capsules under negative pressure or for reduced capsule volume. Based on nonlinear shell theory and the assumption of a hyperelastic capsule…
