Calculating breaking point of an egg

    calculating breaking point of an egg ....

    A general engineering question, how would i go about calculating the breaking point of an egg. The shape is what really gets to me. Then theres calculating Ix and stuff. I need help, anyway of going my calculating the breaking stress of an egg (top to bottom) would help. Thanks

    Ostensibly one calculates the shear stress required to fracture the membrane. One the fracture is initiated, it takes less force to propagate the facture. This also assumes an external impact.

    Example of internal pressure/force on egg fracture -
