    Abstract
  • From the point of structure biomimetic, the model of eggshell-like thin core structure was put forward. From the test of model, the press distortion mechanism was concluded and the carrying capacity of egg-like thin shell core structure was depended on material, size and form angle. Applying thin shell theory, buckling critical load of eggshell-like under action of press load was counted out. In addition, limit element unit model was built up and mechanism and buckling mode were analyzed. The theory basis for weight reduction design was provided in engineering in future.
