Resumo: | ABSTRACT This paper examined the properties of goose eggshells to determine possible areas of improvement in egg transport and storage. First, we measured goose egg sizes and performed statistical tests, and found that the major axis, minor axis, and egg-shape index presented normal distribution. Eggshell thickness first increased and then decreased from the blunt end to the sharp end. Second, the shape of individual goose eggshell was measured using a 3D scanner. Volume equation, surface equation, and contour function of goose eggshell shape were obtained, exhibiting a highly symmetrical structure. Finally, goose eggs were compressed along their major and minor axes between two plates. Breaking strength was highly dependent on the shape index. A crack was found on the force point along the major axis of each goose egg. |
