Abstract

Three key engineering properties of eggshell material were measured - linear thermal expansion coefficient, Young's modulus, and shear modulus. The least-squares mean values of the linear thermal expansion coefficient of eggshell were 5.4 × 10-6 mm/mm-°C and 7.3 × 10-6 mm/mm-°C in the meridional and circumferential directions, respectively, the values of the linear thermal expansion coefficient of eggshell were significantly (p <0.001) affected by gage location and direction. The circumferential eggshell modulus of elasticity in the full ring compression test was 19.0 GPa with a standard error (SE) of 1.3 GPa. By applying a point load to the cantilevered eggshell strip, eggshell meridional modulus of elasticity was 208.8 (SE = 19.0) GPa. There was no significant difference (p = 0.16) in the values of eggshell modulus of elasticity for two different specific gravity eggs. However, eggshell modulus of elasticity values were significantly (p, 0.001) influenced by the location of the eggshell strips. In addition, the measured values of eggshell shear modulus were 5.8 (SE = 9.4) GPa and 90.8 (SE = 9.4) GPa in planes normal to the egg's circumferential and meridional directions, respectively. The values of the shear modulus of eggshell were significantly different (p <0.01) for high (≥ 1.085) and low (< 1.075) specific gravity eggs. In addition, there was a significant difference (p < 0.001) between circumferential eggshell strip and meridional eggshell strip shear modulus values.
