Fracture of the eggshell under impact
Original language description
Hen's eggshell behaviour at the impact on a rigid plate is studied. 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.

LOM VAJEČNÉ SKOŘÁPKY PŘI RÁZU
Czech description
V dané práci byla provedena numerická simulace deformačního a lomového chování vejce při jeho dopadu na tuhou překážku. Byl použit program LS DYNA 3D, který umožňuje modelovat i přítomnost kapaliny a vzduchu uvnitř vaječné skořápky. Ukazuje se, že kritická dopadová rychlost závisí na tvaru vejce. Pevnost vaječné skořápky je pak nezávislá jak na tvaru, tak na tloušťce vaječné skořápky.
