“Parameter dependence in the critical behaviour of shell structures: a numerical approach”, Fourth International Colloquium on Computation of Shell and Spatial Structures, IASS-IACM 2000, June 5-7, 2000, Crete, Greece
ABSTRACT: The paper describes how quasi-static, conservative instability problems can be analysed in a multi-parametric settings. The solution methods are seen as extensions to common incremental-iterative strategies, allowing the computations of subsets of equilibrium states which also fulfill some auxiliary conditions, e.g. criticality. A set of carefully chosen numerical examples demonstrates the versatility of the numerical procedures in performing sensitivity analyses for large scale structures.
