From this study , in the case of the stiffness of the spring with zero found interesting behavior is what buckling in the second (secondary buckling) after the first order buckling (primary buckling). Which makes elastica loads has increased. In the case of the stiffness of the springs is less between 0 - 1 found some elastica can support increased loads. Study of the shape of the elastica from the calculation results and experiment are consistent as well.
