Abstract [en]

The contribution describes how the quasi-static, conservative problem of pressurized space membranes, i.e., balloons, can be seen in a multi-dimensional context, and how one- and two-dimensional solution manifolds can reveal further information on the structural response. The discussed viewpoint can be seen as the natural extension of the common one-dimensional path-following methods for load-displacement traces, when additional variables are introduced to describe the parameter dependence in structural response, and in instability analyses. The paper describes the general setting of the balloon problem, and the generalized equilibrium form, with some aspects of its treatment. Numerical examples show applications of these models.
