Garden hose has stopped flow. There is constant static pressure and no water hammer. Why does hose have tear in axial direction at the end of the hose?

Hint: Think of Mechanics of Materials. Thin-Walled Pressure Vessel.

For thin-walled vessels, hoop stress is 2x larger than longitudinal stress, shown in the formulas below:


Because of this, the hose would be more prone to tear in the axial direction (this is assuming that the hose is not reinforced in any specific loading directions).
