The resistance of goose (Anser anser f. domestica) eggs to damage was determined by measuring the average rupture force, specific deformation and rupture energy during their compression at different compression speeds (0.0167, 0.167, 0.334, 1.67, 6.68 and 13.36 mm/s). Eggs have been loaded between their poles (along X axis) and in the equator plane (Z axis). The greatest amount of force required to break the eggs was required when eggs were loaded along the X axis and the least compression force was required along the Z axis. This effect of the loading orientation can be described in terms of the eggshell contour curvature. The rate sensitivity of the eggshell rupture force is higher than that observed for the Japanese quail's eggs.

“…The results on the fracture strength of the whole eggshell show that this parameter is more or less dependent on the loading rate (Carter, 1979;Trnka et al, 2012;Nedomová et al, 2014). The same dependence may occur also for the eggshell membranes.…”

The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from diff erent bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the membrane in latitudinal direction. TIRAtest 27025 tensile testing machine equipped with a 200 N load-cell was used. Tensile deformation exhibits both non-linear as well as linear region. The experiments were performed at fi ve loading velocities 1, 10, 100, 400 and 800 mm.min −1 . The main parameters describing the eggshell strength increase with the loading rate. This dependence exhibits the same qualitative features as the rate dependence of the eggshell strength.

“…[3,5,6] The eggshell strength is also highly dependent on compression velocity. [3,6,7] Altuntas and Sekeroglu [3] and Nedomová et al [8] also investigated the effect of egg shape on the mechanical behaviour of chicken eggs under a compression load.…”

In this study, the mechanical behaviour of Japanese quail eggs was determined in terms of average rupture force, deformation, and energy absorbed during fracture. Eggs were characterized by some physical and geometrical properties, such as mass, length, width, eggshell thickness, geometric mean diameter, surface area, sphericity, volume, and eggshell radii of curvature. Egg samples were compressed along the axis of their symmetry (X axis) and perpendicularly to this axis (Z axis). Four different compression rates were used: 0.0166, 0.166, 1.666, and 5 mm/s. The highest rupture force, deformation at the egg's rupture, and energy absorbed up to the fracture were found when Japanese quail eggs were loaded along their X-axis. The rupture force increased with the compression (loading) rate. The rate sensitivity of the eggshell rupture force was close to that observed for the hen's eggs.
