Abstract

The stability of aircraft structure is one of the important issues in aircraft structure design. This paper conducts buckling analysis on different boundary conditions of column models, conducts buckling and post-buckling analysis on different materials of rectangular plate models and conducts different radii of curved panel models in aerospace structures. The critical loads for the different models were calculated and compared by software simulation and numerical analysis. The first-order modes of 0.01 and 0.05 times as the initial defects have been introduced into the rectangular plate models in order to carry out the post-buckling studies of rectangular plate models.
