Abstract:

Chicken eggs were loaded under two modes (flat, ring) for the measurement of eggshell strength. Based on this, finite element analysis was conducted using two models and their effectiveness was compared. Combined static test and finite element analysis gave the following conclusions: (1) the horizontal diameter of chicken eggs exhibits a higher load-bearing capacity than the small and big ends under the same loading conditions and the load-bearing capacity of the small end is higher than that of the big end; (2) the carrying capacity is elevated with the increasing of horizontal diameter along the longitudinal axis.

Key words: eggshell strength, comparative analysis, stress distribution, finite element analysis
