Abstract


The subject of the work is 5 goose eggshells. These goose eggshells are chosen with egg-shaped index about 0.69. Counter size of each goose eggshell is measured, including counter shape, major axis and minor axis. Both axial compression testing and external radial pressure testing of each goose eggshell are conducted. Then thickness and density of each goose eggshell are measured carefully with the use of corresponding measuring apparatus. Finally, buckling and strength of each goose eggshell are numerically analyzed with using finite element methods. Results show that strength rather than buckling is the main factor resulting in instability of goose eggshells. The research on goose eggshell could provide efficient bionic information for pressure hulls application in deep-sea manned submersible.
