Conference paper


The stability of nonlinear structures is considered, especially having in view the parameter sensitivity of the stability limit load. It is shown that under special circumstances, for which criterions are derived, nonlinear structures behave with a sudden, i.e. non-continuous, change of the limit load if a certain system parameter is varied. Such phenomena belong to the field of the catastrophe theory which allows their classification and useful documentation.
