1. The decrease in strength of an egg shell which is known to accompany an increase in the period of time over which a load is applied might come about by either of two mechanisms: a decrease in the strength of the material constituting the strong, outer layer of the mineral shell, or a decrease in the thickness of this layer brought about by deepening of the crevices that are normally present between adjacent crystal columns in the weak, inner layer of the shell. 2. Experiments designed to discriminate between these mechanisms are described: the results indicate the second mechanism. 3. This mechanism offers explanations for various other shell phenomena, including delayed fracture under a static, cyclical or recurrent load. 4. The main implication for the poultry industry is that any external insult to a shell is likely to weaken it by doing damage that is local, internal, irreparable and cumulative, even though it may be invisible from the outside. |
