The KoiterNewton approach using von Krmn kinematics for buckling analyses of imperfection sensitive structures
We extend the KoiterNewton approach to buckling analyses for imperfection sensitivity structures. We reduce the solution effort for different imperfection cases to a small fraction of the original solution effort of the method. We test two types of imperfection modeling techniques in the framework of a numerically efficient reduced order model. Computational efficiency is ensured by the use of von Krmn kinematics.
