Abstract [en]

The contribution describes how thequasi-static, conservative  problem of pressurized space membranes, i.e., balloons, can be seen in amulti-dimensional context, and how one- and two-dimensionalsolution manifolds can reveal further information on thestructural response. The discussed viewpoint can be seen as thenatural extension of the common one-dimensional path-followingmethods  for load-displacement traces, when additional variables are introduced to describe theparameter dependence in structural response, and in instabilityanalyses. The paper describes the generalsetting of the balloon problem, and the generalized equilibrium form, with some aspects of itstreatment.  Numerical examples showapplications of these models.
