The critical impact velocity at which eggshell damage starts has been determined. This velocity depends on the egg's shape. LS DYNA 3D finite element code has been used for the evaluation of the stress and strain distribution in the eggshell during its impact. This numerical simulation enables to evaluate the eggshell strength. This strength is independent on the egg shape as well as on the eggshell thickness. It seems that this strength is an intrinsic material parameter.
