Buckling behaviour of dual-thickness dished shells under uniform pressure
Forces in Mechanics, 2023 The dual thickness dished shells are made of conical frustum with a closed stiff top at the smaller diameter end of the frustum. The dished shells are categorized as dual-thickness because of higher thickness of the top circular region than that of the ...

Soft Listeria : Actin-based propulsion of liquid drops [PDF]
Physical Review E, 2004 We study the motion of oil drops propelled by actin polymerization in cell extracts. Drops deform and acquire a pear-like shape under the action of the elastic stresses exerted by the actin comet. We solve this free boundary problem and calculate the drop shape taking into account the elasticity of the actin gel and the variation of the polymerization ...
